Rust-Oleum RockSolid® Composite Deck Cleaner - 56 oz.

RockSolid® Composite Deck Cleaner removes tough stains caused by mold, mildew, algae, fungus and moss to prepare the composite deck surface for RockSolid® Composite Deck Refresh. Our gel formula allows cleaning agents to remain on vertical surfaces, such as side rails, longer to achieve the highest effective contact time.
