Unfortunately, not all wood deck cleaners are created equally.  Usually, deck cleaner products that contain some form of chlorine bleach, or sodium hypochlorite, have the ability to take away gray/dull areas while at the same time break apart wooden fibers which makes it difficult for stains and sealers to penetrate into wood properly. This is why so many homeowners only get a single season out of their stains and sealers. Our hand-applied or pressure washer deck cleaners are environmentally safe, use oxalic acid, and are bleach free! Oxalic acid wood cleaners are particularly effective at removing tannin stains and iron stains (a particular consideration with cedar and redwood decks). Oxalic acid wood cleaners are not as effective against mildew. If you have a mildew problem, try a cleaner made with bleach before using oxalic acid wood deck cleaner to attack the tannin and iron stains.
