How to Remove Black Flaking in a Jetted Bathtub

Last Updated: October 21, 2021

By the time you see any type of flaking coming out of the jets of a whirlpool bathtub, it's already too late. The flaking is remnants of bacteria, mostly harmful, condos that have now decayed and are ruining your vision of a relaxing spa bath. However, this wikiHow can explain how to avoid the problem.

Steps

1
Don't use bleach. This is because, over time, it will breakdown gaskets, bushings, etc. Using any dishwashing detergent is also not recommended, since it will put a coating layer on the flaking you are trying to remove.^{[1]

3
Add a non-toxic bio cleaner to the water. Per the instructions on the cleaning product label, normally it is 1 teaspoon or 1 capful, depending upon the bio cleaner.
4
Run the jets. Turn off the air valve if you have one, on high for 10-15 minutes. This allows the bio cleaner to scrape off the gunk (flakes) that are solidified on the pipe and jet walls.^{[3]

- Bio Cleaners use special properties that are ecological, green, and non-toxic and can eradicate bacteria, algae, mold, mildew, dead skin, soaps, and other gunk in the piping and remove them to the sides of the tub.
5
Clean the bathtub. When you have completed the 10-15 cleaning cycle, remove 2 inches (5.1 cm) of water, clean the "ring around the tub", refill with 2 inches (5.1 cm) of water and repeat the process. You will have to add more bio cleaner in as well.^{[4]

Warnings

Even though bio cleaners are non-toxic, and safe to touch with bare hands and skin, it is advisable to use rubber gloves when cleaning the gunk.
