Removes gunk and eliminates stinks wherever water, soap scum, and dirt build up

here's what recent customers have to say

"I didn't even know all that gunk was in my tub!"

-Bernadette J

Yeah, we hear that all the time. Haven't cleaned the tub in years? Just moved into a new home? Do you take baths or give the kids baths often? It's time to flush those jets. Stagnate water in the darkness of the tub's inner workings is the perfect place for nasty black gunk to build up. 

What are those black flakes? That’s bacteria from human skin, mold, mildew, and soap scum that creeps out during baths. It stinks and is unhealthy.

We recommend regular cleanings with Zero Bull Jetted Tub Cleaner for bathing confidently in healthy, clear water. Each 16oz bottle is good for four uses. If it's been a long time since you've cleaned the jets, or want to do a heavy duty cleaning, try running the cycle twice. Consider maintaining a clean tub by regularly running a 5 minute cycle with 2oz of cleaner after each use before draining tub.

Why Zero Bull JTC has full power AND zero danger

Other jetted tub cleaners, like the Oh Yuck brand, use an active ingredient called quaternary ammonium - Quat - or they use Bleach. Quat and Bleach are known to cause lung damage and asthma and can irritate skin and cause rashes.


Tub treatments with Quat or Bleach cause noxious fumes to fill your bathroom and expose you and your kids to the unhealthy chemicals that linger in the air and on surfaces. The corrosiveness of bleach may damage your jetted tub system.

The Hazardous Materials Identification System (HMIS) shows the dangers of Quat and Bleach, including HIGH HEALTH RISK.

Zero Bull Jetted Tub Cleaner does not contain Quat or Bleach.

The JTC patented solution has an HMIS score of 000 (no hazards), has a neutral pH, and is 100% biodegradable in 10 days.
