Quick Overview

Fiberglass should live up to it’s promise of being an easy surface to clean. However, cobalt staining can turn fiberglass into an eye-sore. Cobalt Cure is specifically for “cobalting”; the phenomenon where cobalt is leached from the resin of fiberglass. Cobalt Cure will remove these spots in 3 days or less without draining.


  1. Turn off the pump
  2. Add 2 gallons of Muriatic Acid of 2lbs of No Mor Muriatic Acid or 5 lbs of Easy Acid per 15,000 gallons of pool water to lower Total Alkalinity.
  3. Add 2 bottles of Cobalt Cure per 15,000 gallons and brush the entire pool. Let stand for 24 hours or until spots disappear.
  4. Re-balance pH using pH increaser of Easy pH. Pump may be turned back on once pH reaches 7.2 or higher.
  5. To prevent re-occurrence of cobalting, add one capful of Cobalt Cure per 3,000 gallons every week. If spots begin to reappear, double the dose.

Maintain a Total Alkalinity below 70 ppm.
