Natural Chemistry Spa Pipe Cleanse – Hot Tub Plumbing Flush Before Draining, 32 oz (14234NCM)

Drain day, done right. Every time you drain your hot tub, biofilm and gunk stay hidden inside the pipes and jets – then foul your fresh water. Spa Pipe Cleanse uses enzyme (SMARTZyme) technology to break down that non-living organic buildup so it drains out with the old water.

• Use right before every drain and refill (every 3–4 months)
• One 32 oz bottle treats one full hot tub
• Works with FROG / mineral systems, bromine, chlorine, ozone and biguanide

How to use: Remove the filters. With the water at 95°F or warmer, add the whole bottle and run the jets 5+ minutes (turn them off if foaming gets heavy). Let it circulate overnight, then drain, rinse, refill and reinstall clean filters. Then restart your Spa Frog or @Ease cartridges.
