Flush your whirlpool system twice a month or more, depending upon usage.
- Adjust the jets fully clockwise so there is no air induction.
- Fill the bath with warm water to a level 2" above the highest jets, or leave water in the bath after using.
- Add 2 teaspoons of a low-foaming dishwasher detergent and 20 ounces of household bleach (5% to 6% sodium hypochlorite) to the water.
- Run the whirlpool for 5 to 10 minutes. Then shut off the whirlpool and drain the water.

- Clean bath surfaces as needed with recommended cleaners.
