Hot Tub Things® Stain & Scale Control – 32 oz Spa Mineral Remover

$27.50
Description
Hot Tub Things® Stain & Scale Control (32 fl oz) is formulated to prevent unsightly stains and scale buildup caused by calcium, iron, copper, and other minerals commonly found in spa water. Regular use protects your spa’s plumbing, heater, and surfaces from corrosion, staining, and rough scaling. It works with all spa sanitizer systems—chlorine, bromine, salt, or biguanide—and helps maintain water clarity by sequestering problem minerals. Ideal for both fresh fills and weekly maintenance.
