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.

How to Prevent Hot Tub Foam

  1. Prevent foam by showering before soaking in the hot tub. Wash off all the soap residue, makeup and other body chemicals.
  2. Make sure bathing suits are cleaned and rinsed with fresh water before getting in the hot tub.
  3. Don’t go underwater. Long-haired soakers should wear a baseball cap to keep their hair up.
  4. Don’t buy cheap chemicals. Get the right chemicals from a trusted source like Ultra Modern.
  5. Don’t drink in the hot tub to avoid the risk of spilling it in the water.
  6. Drain and clean a hot tub regularly. Do this every 3 to 4 months.

Here’s How to Get Rid of Hot Tub Foam

First, get the water tested (we do this- bring us your water sample!). Make sure the pH, alkalinity and sanitizer levels are good. This is also a good time to check for TDS.

High levels of TDS can cause foaming. TDS is caused by an overload of chemicals and other solids into the water that build up over time. The only way to reduce TDS is to drain and refill.

1. Drain and Refill

This is the most direct way to get rid of foam – start from scratch.

Drain and refill the hot tub every 3 to 4 months, and more often if it’s used frequently.

2. BioGuard Anti Foam

Another option is to purchase an anti-foam chemical such as BioGuard Anti Foam that quickly gets rid of the foam.

Let’s say you’re having a hot tub party, or just want to take a soak after a long day of work – in these cases, you probably don’t want to take the time to drain and refill, you just want to use your tub.

If the foam continues, work on draining and refilling.
