Stain Prevention & Remover

Removes Metal Stains and Scaling

Stain Prevention & Remover is a professional strength blend designed to remove and control metal based staining on pool surfaces as well as water discoloration. Stain Prevention & Remover also helps keep scale from forming on surfaces and reduces the likelihood of buildup in filters and on pool equipment. Both stubborn old metal stains and existing scale buildup may require a complete cleaning of the surface prior to using Stain Prevention & Remover.

Stain Prevention & Remover sequesters (picks up) the material causing metal stains and scale and holds them in solution. Dissolved metals and minerals (such as iron, calcium, manganese, and magnesium) and corrosion of metal pool fittings will often cause metal based staining and/or scaling that can be treated with this product.

If stains are not removed, they may be old and require complete cleaning of the walls or they could also be stains of a non-living organic nature (example -tannins of leaves, acorns, etc). Stain Prevention & Remover is not effective on non-living organic staining.
