Spa Marvel Cleanser is a fact-acting proprietary cleanser that penetrates deep inside your spa’s plumbing and equipment, removing organic, mineral and chemical contaminants.
Directions: Open all jets. Remove filters. Pour 1 bottle of Spa Marvel Cleanser into existing water. Turn pumps on high for 1 hour. If the spa is less than 3 months old, or if Spa Marvel Water Treatment is in the existing water, drain the spa after 1 hour. Otherwise, leave the Cleanser in the water for at least another 23 hours before draining. Rinse and refill.
