KleenStart puts the cleaning power of pure oxygen into your hands. As it dissolves, the crystals of KleenStart release the oxygen bound up inside them—giving you nature's own way of cleaning and brightening. Perfect for siding (both wood and vinyl), decks, roofs, tents, Log Homes, outdoor furniture—anything and everything that requires a good deep-down cleaning and brightening.
This is the greatest cleaner for my wood log siding! The 10 minute wait before power washing was adequate for all but a couple of heavily discolored areas which required a second application. I highly recommend this product!
