Description
SpaGuard Stain & Scale Control for Spas & Hot Tubs - 1 Pint
Weekly Protection Against Scale, Stains, and Mineral Buildup
SpaGuard Stain & Scale Control is a concentrated liquid formula designed to help protect spas and hot tubs from scale formation, cloudy water caused by high calcium levels, and stains caused by metals such as iron, copper, and manganese. In warm spa water, minerals and metals can quickly lead to buildup on spa surfaces, heaters, piping, filters, and circulation equipment, making consistent stain and scale control an important part of routine hot tub maintenance.
This 1-pint bottle is a convenient size for weekly spa care. Simply add the recommended dose directly to spa water with the pump running and aeration off. The formula helps bond to troublesome metal ions and calcium-related contaminants so they can be managed through circulation and filtration before they become visible stains or scale buildup.
Use SpaGuard Stain & Scale Control weekly to help prevent new scale and stains, or as directed when fresh metal stains or some scale buildup are present. For best results, start with a clean filter, maintain proper water balance, and clean filters regularly with SpaGuard Filter Cleaner.
