Hot Tub Stains & Scale

Hot tub staining and scale can come from metals, minerals and water-balance problems. Warm spa water can make deposits form quickly, so early identification matters.

Stain or scale?

A stain is discoloration on the surface. Scale is usually a rough or crusty deposit. The treatment strategy depends on which problem you actually have.

What to check

  • Test pH and the other balance parameters recommended for your spa.
  • Consider whether your fill water contains metals or high mineral levels.
  • Inspect heaters, jets and the waterline for additional deposits.
