RE: Wood and Deck Cleaners
Quoting andy broughal:
I need to wash a cedar shingle home before applying semi transparent stain. It's 8 years old and has Maibec cedar shingles with manufacturer applied bleaching oil. There is mold, mildew, and tannin staining.Any suggestions?

You may need to use the RAD Stain Stripper and Brightener kit to remove the Bleaching Stain. This will allow the new semi-transparen t stain to properly soak into the shingles.

re: Penofin on the mahogany
Strip and remove the Penofin with the Restore A Deck Stripper and Wood Brightener. Switch to Armstrong Clark in Amber or Mahogany colors.

Hi,
Initially we used Penofin on the mahogany floor of my screened-in porch. Two years ago, my husband reapplied, but a little too much and it really never dried well. Now parts of the floor are in need of re-sealing, other parts are still dark from the excess Penofin. How do I restore my formerly beautiful floor?

re: not damage the aluminum railing components & the copper flashing
You cannot get the RAD Brightener on the unprotected aluminum. It may "spot" it. The cleaner might be okay but should be protected as well. You would have to plastic wrap all the aluminum well to avoid this from occurring. I doubt the copper flashing will be an issue as it is not visible.

FYI, all cleaners and brighteners will have a potential issue with this railing type.

I have a new ipe' deck. The top & bottom rails are ipe' but the balusters are powder coated aluminum. See railing product here: www.decksdirect.com/.../

I also have copper deck flashing.

I have purchased the Restore-a-Deck cleaner & brightener product and see that I need to avoid getting those products on metal surfaces. I am concerned about my ability to keep the cleaner & brightener entirely off the railings & flashing and fear I might damage those metal component of my deck.

How can I be confident that I will not damage the aluminum railing components & the copper flashing?

re: DECKBRITE PROBLEM
Wolmans Deckbrite is not a traditional wood brightener. Try one of these to lighten the wood:

DeckBrite problem
I used DeckBrite to prepare my new redwood steps for treatment. I followed the instructions exactly (though used a garden hose rather than a power washer to do final rinse). The redwood dried dull and dark. In addition, on areas where it dripped on the side of the steps (and I didn't know it dripped) it has stained the wood very dark. What can I do?

Wolman DeckBrite problem
I used Wolman deck brite to clean my new redwood steps after they'd gotten dirty, and as a way to prepare them for a treatment. But even though I followed the directions on the DeckBrite package, the product dulled my redwood boards. They now look darker and duller. I used a brush to clean after the foaming time, but have not used a power washer. Would it help if I used a power washer?

Cleaning a 1yr old cedar deck - Metro Detroit, Michigan
Last summer I installed a new cedar deck that faces south and is uncovered. I followed all you recommendations for cleaning and preparing prior to using Armstrong & Clark stain. Staining was completed Sept 2014. The deck still looks great but is 'dirty' in spots from our harsh Michigan winter. I do not think I have to re-stain the deck yet, but I'd like your advice for what to use for a simple cleaning. I'd like to avoid re-staining since it's only been 8 months since original stain and it still looks great. Any ideas?

Apply one coat of stain this year and another light coat to the floors next year if needed. You are on edge of needing the Restore a Deck 300 or the 600. Hard to say for sure if the 300 will be enough. The RAD will not remove the inks stamps. You will need to sand this off first then use the prep kit.

cleaning a deck
It's been about 2 months since I've stained my deck with a Armstrong semi- transparent stain. I want to clean the deck. I still have some restore a deck cleaner & brightner left from when I stained it . Can I use the just the cleaner or do I have to use both. My main concern is that the cleaner is too strong & will remove some of the stain I just put on. Or is there something else I can use.

hello, i have used the deck cleaner and brightener with excellent results, have also used a recommended stain that i am very happy with. now the problem, i have a 12 foot long 2 inch wide strip i need to add to the deck.

i have the deck cleaner and stain left over, but no brightener. was wondering if there was anything you might recommend i could use, not sure if i am looking for acid or base. seems silly and expensive to order a whole bottle of brightener for such a small amount any help would be greatly appreciated

No you cannot use the injector tube to apply a deck cleaner. Bets to do in small sections so it does not dry out.

cleaning
Sir, Can I use the tube on my pressure washer, the one that drops into a bottle to mix the water and whatever. I want to clean my deck first and have read you tips but it does not say I can do this. It says to wet deck and then apply cleaner and then wash off. Why can't I do it all at one time using the mixture tube and then rinse with clean water when done. Also I have a big deck and am afraid it will dry out before I can get it all done. Also I am 73 and this would work a lot better for me. I bought your products last year and want to put them on shortly, weather permitting. Thank You DuWayne

re: retired teacher
More than likely your mixture will result in mold growth. It would be better to use a wood preservative such as the TWP. It does come in clear and would offer much better protection as it is an EPA wood preservative.

retired teacher
I just cleaned and brightened my deck with Restore A Deck products. I applied citrus solvent and tung oil as a finish. I'm interested in preserving the wood and not in coloring it. If it goes gray - fine, but want to reduce the drying cracking and save the wood. I live in SC so lots of rain. I'm not interested in coloring the wood - causing wear paths over time. My impression is "I can clean regularly and apply more oil maybe every 2 years or so. Can you advise on my current course and better alternatives?

khw, typically you need to wait 24-48 hours for letting the wood dry.

wrong 15 minutes
well, I let the wrong solution stand for 15 minutes ( the cleaner versus the brightener).
BUT it came out lightened and blindingly bright anyway. Beginner's luck, I guess.. plus it was a brand new deck, so not that dirty. Was just too eager to use the product and get to the job..

RAD
Hi,
rained mon/into tues early morning.. cleaned 9 month old pressure treated lumber deck with RAD Tuesday.. no sun..deck stayed moist due to previous rain.. applied with cheap sponge mop,lightly scrubbed with deck brush.. let stand 15 minutes..rinsed off thoroughly.. applied RAD brightener. The deck looks fantastic. BUT.. you recommend 48 hours without rain before staining with AC stain.. then at least 12 hours thereafter for stain dry time.
For some reason we are having a rainy summer here in northern Ohio. It RAINED AGAIN last night around 8 p.m. for a little bit..
I was going to stain deck on Friday.. NOW with the rain of last night I must stain on Saturday.. and hope the weekend 30 % chance holds off.
No trees near deck. southern exposure..full sun when there is sun.
QUESTION: Must I wait 2 days.. i.e. Saturday to stain or can I get away with staining LATE FRIDAY afternoon?
Thank you

New cedar deck - cleaner?
I have a new cedar deck that is ready to be sealed. I'm planning on TWP 1500 in honeytone.

I'm confused about which cleaner to use. The deck doesn't have any previous sealer, so I just need something that will help remove any mill glaze (doesn't seem to be any, water soaks in), any grime I've accumulated since it was built about 3 months ago, and some minor water staining from washing and rain.

Thanks!

re: Can't find earlier post re. advice for product to use on redwood decks
Lori, I am sorry but I do not remember the original post. Most likely if it was a water based stain then I suggested the Defy Extreme. TWP 1500 should work as well. You can get samples to test out if needed.

Can't find earlier post re. advice for product to use on redwood decks
Hi - I wanted to refer back to the stain you mentioned I might try - it was a waterbased one for a redwood deck railing in San Francisco that had been treated one year ago with a water-based fire retardant product. Now I can't find your posted answer - where did it go? Also - I think I would like to use TWP1500 on both the untreated horizontal part of the deck as well as the fire-retardant (Flamestop II) treated railings. Is that generally a risky move? If so, would I be better off using the water-based stain you recommended for all the surfaces? Thank you very much for the help. Your site is terrific and helps the newbie a lot.

Cleaning and Re-Sealing a Mahoghany Porch
I had 2/3 of a Mahoghany porch installed last year and used a Cabot stain. It did not take properly and the wood is dirty and blackish, old looking and needs to be cleaned and re-sealed/resta ined. It was not washed after the sanding and the company advised us that it was not prepared properly. The humid weather left it tacky and it left marks on it several weeks afterwards, with a lacklusterr dull dirty scuffed up finish. This year, I just had the remaining 1/3 of the porch done with the same Mahoghany wood. How do I clean the old wood? Can it be power washed or must it be done with a deck cleaner? We want to use a different company with UV protection for the entire porch floor. Thanks.

re: Homeowner
Ron, clear coatings with no pigment offer little to no UV protection. The best clear on the market is the Defy Extreme Clear. It would be best to remove the Thompsons first with a deck stain stripper followed by a wood brightener. Restore-A-Deck (www.opwdecks.com/.../) makes very good products for this. It will remove the Thompsons and you can clean and re coat with the Extreme annually.

Hi,
We have a doug fir deck that's been treated annually for the last 3 years with Thompson Water Seal (which apparently isn't the best choice). The deck's covered with a metal roof, but still gets plenty of sun on E, S, and W as we live just E of Albuquerque, NM (an arid, very sunny, high elevation climate). Despite the drawbacks, we still want a clear sealer with no added stain. My questions are: 1) what are my best choices, and, 2) what preparation beforehand would be required (i.e.How much cleaning? Any concerns with residual T. Water Seal? etc. and, 3) Is annual application sufficient? Thanks! Your website's terrific! Ron

re: Advice needed on TLC for a weathered deck
I would use a stain stripper (www.opwdecks.com/.../). It will remove the dirt, grime, and old stains. Nothing wrong with using a pressure washer when using at a light pressure and more for rinsing. The better you remove the old coating the better the new and old wood will match. Make sure to use a wood brightener too!

Advice needed on TLC for a weathered deck
We have a deck that is about 20 yrs old. It has not been properly maintained and it is weathered and has mold and mildew. We just recently had new rails built and a few boards replaced. Some of the wood was salvagable but just needed lots and lots of TLC. The new wood is the light blonde color and the old wood appears to have a red tinted stain. I spent the day using a deck cleaner and about 1/2 of the deck's mold/mildew has been removed (that's how I saw the stain color) but the other part still looks very grey and dirty. Should I continue to work on the other half of the deck to see if it can get cleaner, and what would everyone recommend OR should I use a stripper? I am just lost at this point and don't want to end up with a crappy deck again. I realize the woods won't match perfectly, but I am hoping when we go to stain it in about 6 months it will blend it (if we use a colored stain). Any advise is appreciated. Oh and I don't use a power washer because that is actually how I ruined some of the boards to begin with. :sad:

re: is Restore a Deck also enviromental safe
Yes Restore-A-Deck is environmentally safe wood cleaner and brightener. Both TWP 100 Series and Defy Extreme will offer excellent UV protection for your Cypress deck. You must have a tint though as the clears will not last more then 6-12 months. The pre tinted colors will last 2-3 years in most scenarios on a horizontal surface and longer on a vertical surface.

I have just installed a beautiful ipe deck. I have sealed it appropriately and it looks great. However, typical dirt from trees and the kids and foot traffic needs to be cleaned regularly. I can of course sweep it and I do, but once and a while I'd like to clean it. The only cleaners I see for ipe decks are the terribly strong ones if I were getting ready to reseal. That's not what I want. Can you recommend something for daily....well, weekly cleaning?

re: Strongest wood deck cleaner?
Deck cleaners are designed to remove dirt, grime, mold, graying and or prep a stain for a reapplication. They do not remove or strip stains. The Restore-A-Deck cleaner is an excellent product and will do all of the above.

Perhaps you are trying to remove an old stain. If so then you would need a stain stripper not a wood cleaner. In addition all deck cleaners need to be scrubbed with a stiff brush or lightly pressure washed.

If you can be more specific as to what you are trying to clean or remove then I can help point you in the right direction.

re: used brightener then stained with Armstrong-Clark stain
I would look at the Restore-A-Deck (www.opwdecks.com/.../) Products for prepping for re-coating.

It depends on how deteriorated the 10 year old fence stain is. If almost completely gone then a deck cleaner (www.opwdecks.com/.../) will suffice. If not then a deck stripper (www.opwdecks.com/.../) will be needed.

re: Deck Cleaning
Wood cleaners are designed for outside wood and definitely will prep the deck better then a all purpose cleaner.

Will it really matter that he did not clean it with a "wood" cleaner? The deck was not that dirty before, but is graying so I will be staining here shortly. Guess I am trying to figure out if I should go back over his work with a wood cleaner, then brighten, then stain or if I can go straight to the brightener step.

One last question (I hope)...

Do you know if the Flood cleaner/brighte ner which is a single product unlike the others which are separate is it any good? Seems like it would save a little time if so but I'm leary about it's effectiveness if they've combined the cleaner and brightener.

Thanks again!

re: recommended Cleaner / Stain
1. Not much difference in ease of use or results when using a brightener. Cleaners can have different results but all three you mentioned work very well with RAD and Defy being our top sellers.

2. Suggested TWP based on experience, your climate, and location.

recommended Cleaner / Stain
Hi,

1) Which product do you think is best for cleaning/bright ening: Restore-A-Deck, TWP or Defy? Is there much difference in ease of use or effectiveness?

For stain I recall you recommended I use TWP rather than Penofin or Preserva Wood for a deck in Northern CA. Is that based upon your experience with each product or something else?

Thanks,

re: First application of deck stain
You should use both a wood cleaner and a wood brightener to prep the deck. You should wait at least 24-48 hours after prepping before staining.

I would not use the Arborcoat. Has many issues. Cabot is better but is still an average stains at best.
Quote
First application of deck stain
I am ready to stain our deck that was completed 10 months ago.

Do I need to do anything other than apply a cleaner and then stain the deck?

If I'm guessing right about just using a cleaner, how long after I clean the deck should I wait until I apply the stain?

I am going to use a semi transparent non oil base stain and thinking about either Cabot or Benjamin Moore Arborcoat. Any recommendations?

Thanks

re: Do I have to strip or will cleaning/bleach ing be adequate after using Defy Clear Expoxy or Defy Extreme Clear?
You can clean with the Defy Wood Cleaner then apply the Defy Extreme Clear without the need for stripping. The Defy Extreme Clear is basically the same as the Defy Epoxy UV Clear but with the added nano particles of zinc oxide. This will aid in color retention and help substantially with mold/mildew.

Do I have to strip or will cleaning/bleach ing be adequate after using Defy Clear Expoxy or Defy Extreme Clear?
I used Defy Clear Epoxy Wood Finish 2 years ago. I like it because the pressurized wood looks natural. No wear and unevenness but there is now some mildew. My question is can I just use the oxygen based bleach cleaner that is environmentally safe to prepare it to again use the Defy Clear Epoxy wood Finish or to use the Defy Extreme Clear Wood Stain? And if I use the Defy Extreme Clear Wood Stain, in years to come, would I have to strip it or could I just use the oxygen-based bleach - cleaner to prepare for another job?

I applied Defy for hardwood to my deck last year and it is in excellent shape. Do you recommend annual cleaning with one of the Defy cleaners or just washing it off with a mild cleaner?

re: deck on the Jersey shore oceanfront
I would use a deck stripper (www.opwdecks.com/.../) to remove the Cabot Stain. Make sure to neutralize when done with a deck brightener (www.opwdecks.com/.../).

re: Black tannin marks on new deck material
They may not be tannin lines but rust from the rollers. If metal gets into the wood it will rust and turn black. Any good quality wood brightener (www.opwdecks.com/.../) should remove this.

Black tannin marks on new deck material
I have just installed new redwood decking. Many of the boards have repeating black lines on the boards. The supplier says these are tannin lines caused by steel rollers. How can I remove them without harming the wood?

re: Deck Restoration Guru
Very true information. Thanks for the tip!

Deck Restoration Guru
If you bought a wood cleaner/ brightener from one of the big boxes you may have bought a $15 gallon of bleach. Not only will bleach cause the damage that you mentioned, it will dry out your wood. I would reccomend trying to rinse what you can out right away but if it has already dryed try testing the Ph of the wood. If the Ph is anything other than nuetral you will need to find a chemical to balance the ph. If this step is omitted then the life of any future preservative you put on the deck will be reduced. I hope this helps.

re: Wood cleaner bleached/discol ored my concrete
Brighteners are very mild acids. Acids in general can etch/clean concrete surfaces. It is possible that the Brightener you used cleaned the concrete. Does it look lighter in color?

Wood brighteners are mild acids and typically are not bleach. They should not effect your concrete or shoes. Which brand did you use?

Wood cleaner bleached/discol ored my concrete
I have some redwood retaining walls that needed cleaning. I used a wood brightener, and this product looks like it bleached my concrete patio and adjoining concrete wall. It also bleached my canvas shoes, and the sidewalk in front of my house.

I tried scrubbing this product off, but it won't budge.

What happened? How can I remove this discoloration from concrete and cotton canvas?

What would have been a better way to clean my retaining walls? I still have many more to do.

re: two year old deck
Use one of these wood cleaners (www.opwdecks.com/.../). Any of them will help remove the gray and restore the natural wood.

All of the stains we sell are high end. some though do better in certain climates. Please respond to these questions:

1. Where are you located?
2. Do you have full sun?
3. Do you have issues with mold?
4. Do you have excessive traffic?

re: Durability
Defy is a very good product and is one of our best sellers.

One Time is a not a very good product and their warranty is bull. They charge a ridiculous amount of money for a stain that will turn black in a couple of years. All the warranty will cover is product replacement. They are playing a numbers game with the warranty. I have had numerous customers tell me what a waste of their time and money One Time was. The vendor also claims that the One time cannot be stripped which is a lie. It actually comes off very easy.
Quote
Durability
I'm researching deck stains and as the decks are for rental properties, am mostly interested in durability and minimal maintenance. From what I've read so far, DEFY and One Time seem to be two products that match my requirements. I understand that you sell DEFY and naturally expect that to factor into your answer, but what are your opinions on both and am I heading in the right direction? Thanks in advance.

re: Cleaning markings off new pressure treated decking lumber
A deck cleaner will not typically remove these ink stamps unless the wood is weathered/gray. Sanding is probably your best bet. Problem is that you may leave sand marks all over your decking that will show through when staining.

re: Dock turning green
The green is moss/algae and this can grow in wet environments. It also does not matter what stain you use as the moss/algae will grow on top of the stain. Wood stains cannot prevent this from occurring. A periodic mild cleaning will remove this.

Any of the Deck Stain Strippers (www.opwdecks.com/.../) that we sell will remove the TimberOil.

re: IPE Walkway Cleaning
I would use a deck cleaner that contains the active ingredient Sodium Percarbonate, otherwise known as "oxygen bleach". This is considered a mold/mildew remover and is environmentally safe for your plants. Here is a couple that we carry:

Ipe walkway cleaning
We have a client in North Florida with a one-year-old ipe boardwalk to the ocean. The walk is turning a nice weathered gray. However, there are plants on each side of the walk, so part of the walk is shaded much of the day. Also, the neighbors to the south have run their lawn sprinklers off-target, and the water hits the walkway and often leaves the shady sections wet for long periods.
As a result we have dark moldy areas on the walk. They are slimy and slippery to walk on.
What can I safely use to clean the ipe? (The neighbors have finally adjusted the sprinklers.) Thanks!

re: Deck Cleaning
Bleach (Sodium Hypochlorite) is not actually good for wood. It has been proven to break done the lignin. Lignin holds and strengthens the bond between the wood cells. You would be much better off with a Oxygenated Bleach or Sodium Percarbonate. This is much safer and better for the wood. If you are looking for cost effective products, I would suggest a powder concentrate for the cleaner and Brightener. Look at the EFC-38 Cleaner (www.opwdecks.com/.../) and the Citralic Brightener (citralic-brightener.htm) in the 10 pound containers. Each make 20 gallons and would cost less then $4 a gallon when mixed. These are excellent contractor grade products!

Deck cleaning
I have been working to find a good combination of products that will make cleaning decks efficent and less costly.A Baer rep had given me some deck cleaner and I went home and sampled it against bleach on a piece of old weathered deck board.The bleach by far out performed the Baer product and is so much cheaper to buy.My question is as I see how clean and brighter the wood looks after using bleach is there any steps I need to take after the intial cleaning ,other than bleach?Do I need to nuetralize the bleach.There are so many products out there and several contractors have their own formulas.Also using TSP is that necessary to use with the bleach or not?

re: Cleaner for recently stained deck - want to preserve the stain
The Defy Wood Cleaner will remove dirt, grime, mildew but it will not remove stain unless the stain is a transparent that is extremely deteriorated. It will not change the appearance of your solid (opaque) stain. No need to use a wood brightener for this scenario.

Cleaner for recently stained deck - want to preserve the stain
I searched the QA and couldn't find an answer. I'm getting ready to clean a deck with Defy Wood Cleaner that I ordered from you all. The deck is pressure treated pine and was stained with an opaque stain last year. Most of it looks good, but a few places have mildew build up. Will the deck cleaner alter the stain that still looks good? My friend is hoping not to stain again until next year. He just wants a good cleaning. Also, would you recommend using a brightener after the cleaner in this situation?

re: 15 year old PTP deck
You are correct that proper prepping is very important. To be on the safe side I would suggest using a wood stripper. The wood stripper will remove the previous coating. This will help ensure that your new stain will adhere and have the best results. Stripping is not that much harder. Feel free to email me a picture at . I should be able to determine if a cleaner will work or a stripper is needed.
Quote
re: 15 year old PTP deck
How can I tell if the cleaner is doing an adequate job? Is it based on appearance after cleaning or how the new sealer adheres, etc.? Also, I read somewhere that a stripper was needed if water beaded up on the current decking and was not absorbed within 5 minutes. (I prefer to use cleaner because it would be less expensive and probably easier, but I know proper prep is critical and I want to do a quality job.)What is your advice on how to best determine whether to use a cleaner or stripper?
Thanks very much.
Quote
re: 15 year old PTP deck
If you use a wood stripper then you would not need to use a wood cleaner and vice versa. You should use a wood brightener to neutralize the stripper or cleaner.

An oxygenated cleaner maybe good enough if the old finish is very deteriorated.
Quote

My deck (pressure treated pine)is about 15 years old and has been cleaned and sealed a few times using what were probably oil based sealers. It's been several years (maybe 5 or 6) since last sealing, so I'm thinking much of that sealer may have worn off (the deck is looking weathered) and that an oxygen bleach cleaner may be adequate? Or do you think a stripper is needed, and if a stripper is used does that eliminate the need for a cleaner?

thanks for nay advice on this.

re:Deck Stain
There is not a "best" stain on the market. Everything we carry is high end and will perform very well. Certain stains perform better then others though based on where you live, weather, UV exposure, etc.

Any of the wood cleaners will work that we sell. Do you have a previous coating on the wood? If so then you will need to use a wood stripper. In addition you should always use a wood brightener.

Re: How Much Stain Do I Need
1. All wood (even new) should be properly cleaned and brightened. This will ensure the best results. Deck Restoration Steps (www.opwdecks.com/.../)

2. Coverage varies on the brand of stain and the application procedure. It is hard to say. Maybe 3-5 gallons.

re: Cedar House
1. Defy Extreme is not tintable. You would need to use the Defy Hardwood/Cedar that is pre-tinted. It is possible to mix the Defy Extreme Clear with the Natural Pine color. This will give a very light tint and the Extreme protection.
2. Apply Wood Stripper, wash off, apply Wood Brightener while still wet
3. Let dry for at least 24 hours

Thanks

Cedar House
Many thanks
Few follow ups and I will order a few items,
1) I will use the Defy Extreme and take your advice and do some tint. I see the Crystal Clear. Where do I get the tint. What color would you suggest to avoid orange color from coming out (and reduce mold growth).
2)I do have power washer. Do I have to apply stripper, wash it off then apply brightener? Can you use both at same time? Do I need dry time between the 2 products?
3) I assume before I would apply the Defy Extreme I need to let house dry a few days?
Many thanks

re: Cedar House
1. Keeping the natural color from graying is not possible for very long without adding a tint to the wood. Adding a tint will enhance the natural colors of the cedar which is yellow/orange. It is not possible to achieve what you are asking. The best "crystal" clear product we have is the Defy Extreme. It will work for you in this scenario but only for a year or two. Adding a tint will last alot longer.

2. You need a wood stripper to remove the Cabot's. The easiest way to strip this large house would be to inject the stripper and brightener through a pressure washer that is equipped with an injector. Do you have this?

Cedar House
Have new cedar on exterior of house.

1) Want to keep that natural color and not bring out any red/orange color. Also want to avoid greying I often see. Which sealer do you suggest?

2) Also, a Cabot semi transparent sealer was used. It first caused house to turn orange/red. This color mellowed but now lots of grey forming. What specific products to use to clean house now
- if stain was oil based?
- if stain was water based?
Please give me some details on process to clean and the products as I want to make sure to do it right as it is a big job!

200-400 feet for the Hose-Connect Brightener. It does not need to be heavily added. Just needs to get on to the wood to neutralize the stripper or cleaner.

After appying a deck stripper you will need to remove the old stain by either using a low pressure washer or hand scrubing. It would be easier to use a pressure washer but care should be taken not to damage the wood. Here is a link to read more:

To link with my other question
So, as I was saying, I've got a pretty nasty stain that seems to be there for a while. I've heard of an industrial cleaner, but I don't want to use it and destroy the wood. What other type of cleaning product can I use?
Quote
-
That is a good question. Generally the people who clean every few days are just removing general dirt and grime. This can just be done with water and or a broom. Every couple of years you will need to do a thorough cleaning prior to restaining or resealing. This is needed so your coating will penetrate properly.

I have read the questions and comments but have one question of my own. I have been seen many people clean there decks on a regular basis and others who do it a few times a week. Is there something I am missing? I would like to know how often it is necessary and how does it effect the finish and the wood over time.

Thanks for the link. I have a problem with the stop marks, it's a real pain since I'm not physically strong, and I'm wielding a fricken weapon. I'm getting the hang of it though, there's good money in cleaning up porches and decks, since you need good-quality equipment to do it properly.

Pressure Wash a Deck Properly
Pressure Washers can be safe for wood and decks as long as precautions are taken. Excessive force can damage and splinter the wood causing severe damage. The use of proper deck cleaners while using a pressure washer will improve performance and reduce the need for high pressure. Please read these tips for additional info;

How to Pressure Wash a Deck (www.opwdecks.com/.../)
Quote
Pressure washers.
Not sure if that's what it's called or not. Basically those machines that force water out at a pressure so high, it can even clean off things that steel wool can't make a dent in.

Is it safe to use these on painted and varnished wood? Or would it end up stripping them right off?
Quote

If you want to apply a different stain other then the Cabot, then you should remove the coating with a deck stripper (www.opwdecks.com/.../). Using just a deck cleaner is okay if you want to use the same brand, but when changing to a different brand you should remove the old coating.

In general, oil-based stains can attract mold. Some do better then others in wet climates though. If you want an oil-based product then I would suggest either the TWP brand or the Timberoil brand.
