I have a newer(3years old) pressure treated deck, never cleaned or sealed. I started cleaning the deck (starting with the railings and spindles) with the cleaner sold here. It has left behind a fuzzy look. Should I lightly sand the deck before I use the brightener, or do you recommend another solution. Located in NE Ohio.[/quote]
This happens when you are moving a heavy layer of oxidized wood cells. Typically on decks that are left unstained for 1+ years. Yes you can lightly sand or buff to remove the fuzzies, then brighten.
What grit sandpaper would you suggest
