Oxalic acid is the main ingrediant for many of the commercially prepared deck cleaning products, including, but not limited to: Wolmans Deck and Fence Brightener, Flood's Dekswood, & ZEP's Deck & Fence Cleaner.
Of course, some home brews will work better, but generally speaking, they will do a pretty decent job, provided the wood does not have stain, or sealer of any kind on it, and the issue is just natural greying, and dirtiness.
The cheaper prepared mixes only contain a medium sodium hypoclorite content (bleach), and a surfactant. I have "fixed" many decks that homeowners have messed up with this product.
I'll leave alternate cleaning solutions to others to post about. Tony C.
