FROG® Maintain is a potassium monopersulfate-based oxidizer designed specifically for swim spas and hot tubs. Unlike traditional chlorine shock treatments, this non-chlorine formula works quickly to break down oils, lotions, sweat, and other organic contaminants that cloud your water and reduce sanitizer effectiveness.

Key benefits include:

  • Fast-acting formula – Dissolves quickly and works within 15 minutes
  • pH-neutral – Won't disrupt your water balance
  • No chlorine odor – Enjoy a fresh, clean spa without harsh chemical smells
  • Swim-ready faster – Safe to use your spa shortly after treatment
  • Compatible with all sanitizer systems – Works with chlorine, bromine, and FROG mineral systems

This product is ideal for regular maintenance shocking (weekly or after heavy use) and is an essential part of any comprehensive swim spa care routine.
