Stain Prevention & Removal

Natural Chemistry® Metal Free is a powerful, phosphate-free chelating agent designed to prevent and control metal staining caused by iron, copper, and other trace metals commonly found in fill water. By binding to metals in the water, Metal Free keeps them in solution and prevents unsightly surface staining and water discoloration. It’s ideal for use during pool openings, refills, or whenever new water is added.

Safe for all pool surfaces and compatible with all sanitizing systems, Metal Free is especially beneficial in areas with high metal content or when using well water. It won’t affect water balance and is gentle on equipment and finishes.
