Organic Indoor/Outdoor Concrete Cleaner Concentrate, 1 qt

Classic Organic Concrete Cleaner Concentrate is an organic acid replacement technology that has zero VOC and a low PH salt that is used to replace traditional acid, which means there's no need to neutralize. It is 4 to 10 times more effective than citric and glycolic acid and is 4 to 5 times more effective than phosphoric acid when dissolving calcium carbonate. Organic Concrete Cleaner is classified as a mild skin irritant but is non-corrosive to skin, mild steel, and has no fumes. It is approved by the US EPA as a non-food inert ingredient in biocide applications. Non-Hazardous and Bio-Degradable. We highly recommended doing a sample first before applying. It can be used on pool decks, concrete slabs, stone, bricks, and grout. It may be used for both interior and exterior applications in low and high traffic areas within a wide range of climates. It is an excellent cleaner and etcher. It is environmentally safe and cleans up easily with water. Recommended mixing ratio: 1 qt. cleaner to 1 gal. distilled or ionized water. Caution: Surface is slippery when wet. New concrete must cure for 28-days before use.
