Metal Out – 16 oz

$20.98 $16.99

Use Hot Tub Things Metal Out to prevent scale, staining, and calcium build-up on surfaces.

The water used to fill your spa may contain high amounts of metal that can stain or discolor your spa’s surface. The presence of minerals can cause oxidizing and scaling on the shell’s surface and erosion of the heater element. Hot Tub Things Metal Out protects your spa from metal and metal impurities found in spa water by suspending and inhibiting stain and scale causing minerals.

Use: Add 16 oz. to spas up to 500 gallons of water while it is being filled, before any sanitizer is added. Remove and clean cartridge filter within 24 hours of dose with filter cleaner.

NOTE: Draining and cleaning of spa or hot tub is recommended every 3 months.
