SpaGuard Stain & Scale Control | Metal & Scale

SpaGuard Stain & Scale Control protects your spa's shell from two of the most common and frustrating sources of damage: metal staining and calcium scale. It's designed to both prevent and remove staining, and to keep scale from forming in the first place — so your spa stays clean, smooth, and looking new.

Metals like iron, manganese, and copper find their way into spa water through your fill source, and once they're there they can stain the shell with stubborn discoloration. Separately, when calcium levels run high, scale builds up as a rough, crusty deposit on surfaces and equipment. Stain & Scale Control tackles both: it keeps metals locked up and harmless so they can't stain, and it helps prevent calcium scale from depositing on the shell of your hot tub. The result is a cleaner spa, protected surfaces, and far less scrubbing.

Used at start-up and as part of weekly maintenance, it's simple insurance against permanent staining and scale damage. Available in two sizes — a 1 pint bottle and a 1 quart bottle for owners who want a longer-lasting supply.
