Here’s How to Get Rid of Hot Tub Foam

A hot tub can produce a lot of foam on occasion. While this seems fun when you’re in the bathtub, it’s not ideal in a hot tub.

Hot tub foam is caused by the water being “thick.” The air jets activate these tiny bubbles, causing the foam. In this article, we look at how to get rid of hot tub foam.

Here are the common causes of hot tub foam:

  • Hair care products such as shampoo, gel, mousse, hair spray, etc.

  • Body lotions and deodorant

  • Makeup

  • Laundry detergent or soap

  • Cheap hot tub chemicals, too many chemicals, or total dissolved solids (TDS)

  • Drinks

The only thing that should go in your hot tub water are people and and trusted, high quality hot tub chemicals. Anything else can cause foaming and other problems.
