How to clean your wood deck with oxalic acid deck brightener
Even new wood needs cleaning to remove mill scale, making the surface more porous to easily absorb deck stains. Defy Wood Brightener is the 2nd step in a 3 step system to maintain your deck and keep it looking like new. The 3 steps are:

  1. Brighten using Defy Wood Brightener
  2. Apply Defy water repellent wood stains

re: how do you apply defy deck brightener?
Best to spray on then rinse after 10-20 minutes. No need to scrub.

how do you apply defy deck brightener? Is there an oxalic acid brightener that you can spray on, wait, then rinse or do you have to spray, then scrub, then rinse?

re: Deck refinishing
Oxalic acid is a wood brightener not a wood cleaner.

The only way to get it lighter and even is to use a stain stripper to remove the buildup layers of old stain then use the wood brightener to neutralize.

Deck refinishing
I have protected my PT deck for several iterations (the last 6 yrs) with Defy Epoxy Stain (Natural). Each application has made the deck slightly darker. Prior to this year's planned restaining, I was wondering if in addition to cleaning with an oxalic acid wood cleaner, that a wood brightener would do any good. I am concerned about the deck looking blotchy as the wood brightener would not brighten where the epoxy stain was still effectively sealing the surface. Any thoughts?

re: Furniture refinishing
No. The Defy Wood brightener does not "brighten" stain or water marks. It brightens or neutralizes wood.

This product is also designed for outside wood, not interior furniture. We do not sell products for furniture.

Furniture refinishing
I am attempting to refinish a solid birch wood bedroom set. This is my first attempt at doing this so please bear with my total lack of know-how. I have sanded my heart out but I cannot get an even color. I realize that birch is typical of this but I believe that it may have more to do with the previous stain penetrating deeper in some areas than others. There are also black water marks on the legs of the headboard and footboard. My question is, would Defy Exterior Wood Brightener be good for removing the last vestiges of stain and brighten it up? And if I used this product, would it then matter which new furniture stain I applied?
