Jacuzzi® Stain & Scale
Jacuzzi® Stain & Scale is a concentrated liquid formula designed to prevent and remove scale buildup and staining in hot tubs. It sequesters hard water minerals like calcium, iron, copper, and manganese that cause unsightly deposits and reduce efficiency. Regular use keeps spa water clear, protects equipment, and maintains smooth, clean surfaces for the ultimate soaking experience.
Why Use Stain & Scale?
-
Protects Equipment: Prevents scale that can clog plumbing, reduce heater efficiency, and damage pumps/filters.
-
Maintains Appearance: Stops mineral stains and chalky buildup on the acrylic shell and jets.
-
Improves Hygiene: Keeps surfaces smooth and easier to clean, reducing areas where bacteria can hide.
