From verified Amazon customer reviews — our highest-rated product.
Effervescent tablets that flush the trapped residue hiding inside your jet lines. One tablet, a 15-minute cycle, and the dark flakes coming out of your tub jets are finally gone.
Why customers love it
- ✓ Flushes hidden buildup from jets — penetrates whirlpool and jacuzzi jet lines to dissolve trapped soap scum, body oils and biofilm.
- ✓ Septic-safe formula — strong enough to clean, gentle enough for septic systems and home plumbing.
- ✓ One-step, no scrubbing — just fill, drop, and run the jets. The tablet does the work.
How it works
- Fill the tub with hot water above the jet level.
- Drop one tablet and run the jets for 15 minutes.
- Done — drain, rinse, and repeat once a month.
Compatibility
Works with all jetted tubs: whirlpool baths, jacuzzis, hot tubs, spa tubs, air-jet and water-jet systems.
FAQ
How often should I clean my jetted tub?
Once a month if used regularly. Quarterly if used occasionally. Always run a cleaning cycle if the tub has been unused for more than a month.
Why do dark flakes come out of my jets?
It's biofilm: a mix of soap scum, body oils and bacteria building up inside the pipes. The tablet dissolves it in the cycle.
Is it safe for septic systems?
Yes. The formula is septic-safe and home-plumbing friendly.
Can I use it on a regular bathtub?
It's designed for jetted/whirlpool systems. On a standard tub it works as a soak cleaner but isn't necessary.
How long does a pack last?
12 tablets = 12 monthly cleanings, or about one year of regular maintenance.
Our promise
30-day money-back guarantee. If the first cycle doesn't visibly flush residue out of the jets, we'll refund you.
