This stuff is AWESOME! Spray it on and it dissolves mold and mildew on wood decks, vinyl siding, concrete porch/sidewalks. Way better than any other cleaner, and I have tried OxyClean solution, several deck washes, and house washes. None come close. Five minutes without scrubbing and just hose or pressure wash off. It will clean the wood before you even rinse.
