Using a exterior stain stripper is typically needed if the old stain or sealer has failed by peeling, wearing unevenly or when changing brands of stain. A stripper will aid in removing the old stain by softening the bond between the stain and the wood cells. This allows easier removal with a light pressure washing or stiff scrub brush.
The process of using a wood stain stripper is incorrectly considered difficult. In fact it will save a substantial amount of time while reducing the any chance of damage to the deck with a pressure washer.
