It's a myth that's been discussed for a long time that bleach will damage the wood. " MYTH BUSTED" I'm maintaining decks,fences ,cedar houses etc that I've cleaned with bleach since I've started in wood restoration 14 yrs ago. When a good oil base stain is used on a deck it will keep the wood from drying out that can be caused by the bleach.
See pics below how this deck was cleaned with the same mixture and process i mentioned in the previous post.
Yeah, I think Shane has crushed that myth easily. I'm guessing the companies selling high priced percarb cleaner don't want you using bleach and cutting into their dough. I've had great results with BOTH cleaners, and am now only using bleach in many cases.
