Thompson's WaterSeal Heavy Duty Deck Cleaner is specially formulated to remove weathered clear and tinted waterproofers and semi-transparent stains from decks and other exterior wood surfaces. It also restores the natural color to severely weathered and discolored wood without bleaching. In addition, unlike many competitive products, this deck cleaner is self-neutralizing, which means you will not need to apply another solution before deck waterproofing or staining.
