In The Swim Stain Remover for Swimming Pools - 1 Quart

The In The Swim Stain Away Pool Stain Remover effectively prevents and removes mineral stains from iron, copper, and magnesium, as well as scale buildup. It is essential in areas with high iron or copper levels or well water. The active ingredient, Hydroxyethylidene Diphosphonic Acid at 13-15%, chelates copper and iron, making it safe for all pool surfaces and ideal for well water use.

To use, simply add 15 oz. per 10,000 gallons to the pool while it circulates for 3-4 hours. For tough stains, double the dosage. Regular use is crucial as Stain Away degrades in sunlight and chlorine. After the initial treatment, a weekly dose of 5 oz. per 10,000 gallons is recommended. For existing stains, apply 30 oz. per 10,000 gallons directly.
