How to Clean the Jets in Your Bathtub

I had the opportunity to talk to Scott Bakke, the plumber that installed this Jacuzzi® tub. I asked about jetted tubs in general and about the black flakes and brown scummy bits that sometimes appear when the jets of a tub are turned on.

Those little bit and pieces are actually mold and mildew. Yes, as it turns out, mold and mildew can -- and does -- grow in the pipes inside your jetted bathtub because there is always a little moisture in pipes. This is different than a hot tub/spa which is usually full and holding hot water so not as big of a concern.

Bakke tells me that it's important to clean the jets regularly to keep your tub enjoyable and offered this easy and inexpensive way to do it. 

1. Check your manufacturer's instructions to be sure nothing you are using is bad for your tub. Once you have confirmed that, fill the tub to about 3-inches higher than the highest jets. 
2. Turn off the air induction valve. 
3. Add 1/4 cup of low foaming disinfectant like Cascade dish washing powder. 
4. Run the jets for 5-15 minutes at the highest pressure. 
5. Drain the tub and refill with cold water. 
6. Run the jets again for between 5-15 minutes as a rinse cycle. 
7. Drain and wipe clean with a soft towel. 

Hope that helps and if you have any tips please share them in the comments.
