Thompson’s Exterior Multi-Surface Cleaner with oxy-foaming action is formulated to remove dirt, mildew, and other stains from a variety of outside surfaces including wood and composite decks, concrete, masonry, and even some fabrics.
The powerful oxygen cleaner contains no bleach, making it gentle on surfaces. Apply with a pump up sprayer or watering can and then allow 5-10 minutes for the cleaner to soak. Scrub the surface with a stiff brush, then rinse it off with a hose. Thompson’s Exterior Cleaner is available at The Home Depot.
