Master Clear Oxidizer Shock 2 lb | Non-Chlorine Spa & Swim Spa Shock

Description

Keep your hot tub water sparkling clean with Master Clear Oxidizer Shock. This professional-grade non-chlorine oxidizer rapidly eliminates non-living organic contaminants that build up from normal spa use, including body oils, cosmetics, lotions, perspiration, and other waste that can lead to cloudy water, odors, and reduced sanitizer efficiency.
Unlike traditional chlorine shock, Master Clear Oxidizer uses potassium peroxymonosulfate (MPS) to oxidize contaminants without significantly increasing chlorine levels. It helps reactivate your existing sanitizer, allowing chlorine or bromine to work more effectively while reducing downtime between soaks.
Regular use improves water clarity, reduces unpleasant odors, and minimizes sanitizer demand, making it an essential part of a complete Master Clear water care program. The active ingredient is 42.8% potassium peroxymonosulfate, making it suitable for routine maintenance in hot tubs and spas.
