#1 Deck Wood Cleaner is a powdered concentrate that is mixed with water. It safely cleans and restores the natural beauty of exterior wood. This product also cleans weathered composite lumber, removing mold, mildew and algae along with the silver gray color that can develop over time. Restores all wood surfaces to their original appearance. #1 Deck Wood Cleaner will not harm wood fibers, pets, grass, or most plants. If the wood surface has a previously applied stain that is still intact, use #1 Deck Wood Stain Stripper instead of the cleaner. Note: It is not necessary to use both the cleaner and the stripper. Choose whichever is appropriate for your situation.

#1 Deck Wood Cleaner removes dirt, grime, mold and mildew stains, and weathered graying from horizontal and vertical wood surfaces. It is recommended for surface preparation prior to application or reapplication of wood stains. For best results use #1 Deck Wood Stains. This product is step 1 of a 3 step system.
