Description

Natural Chemistry StainFree is designed to remove metal staining from swimming pool surfaces using a powerful 100% citric acid formula. Iron, copper, and other dissolved metals can leave unsightly stains on pool finishes, liners, steps, and other surfaces. StainFree helps eliminate these stains and restore the pool's appearance.

The phosphate-free formula is compatible with all pool sanitizing systems and can be used on virtually all pool surfaces, including vinyl, fiberglass, and plaster. Its concentrated formula works to dissolve metal staining without requiring harsh acids or draining the pool.

For optimal results, follow treatment with Natural Chemistry METALfree to help prevent metals remaining in the water from causing future staining.

Pro Tip

Lower chlorine levels before treatment and avoid shocking the pool during the stain removal process. High sanitizer levels can reduce the effectiveness of metal stain treatments.

Installation Tips

Balance water chemistry and lower chlorine levels to 1 ppm or less before treatment. Apply approximately 1 lb per 10,000 gallons of pool water according to label instructions. Follow with METALfree treatment and clean the filter after the stain removal process is complete.
