Why Does Water Foam?

In order to foam, water requires two things; air and a surfactant. Surfactants are molecules that reduce the surface tension of water; making it easier for oils and water to mix. The combined oils and water then form a thin “skin” on the surface of the water. When air is added to the hot tub water from the jets, the “skin” traps some of that air; forming a bubble. The more surfactants and air that are present in the hot tub, the more bubbles you will get and the longer they will last. Eventually, the bubbles will begin to group together, causing a buildup of foam.

Common Causes of Foamy Hot Tub Water

The primary reason why foamy hot tub water can be so hard to treat is that no matter how hard you try, there will always be some level of surfactants and oils in your hot tubs water. The key is to keep the amount of each below the point at which they can cause foam buildup. There are multiple reasons why oils and surfactants can build up in hot tub water; with each of these potential reasons requiring different treatments to fix. The good news is that foamy hot tub water is easily treatable, as long as you know what is causing it. The most common way that surfactants enter hot tub water is through soap residue on your skin and bathing suits, with the biggest culprit being your bathing suit. What causes oils and surfactants to build up and cause foamy water in hot tubs? The most common causes are:

  • Soaps and detergents
  • Oils and lotions.
  • Biofilm build-up.
  • Poor water balance.
  • Soap and Detergents

Oils and Lotions

The most common cause of foamy water in hot tubs is a buildup of oils and lotions in the water. Although they don’t really have any negative effects in low amounts, over time these substances can build up in the water, especially on or near the surface of the water. If left untreated, the oils will build up to a level that will cause foam. Every time you use the hot tub, you can potentially add a variety of oils and lotions to the water, including:

  • Body oils.
  • Deodorant.
  • Beauty products.
  • Body lotion.

Preventing Foamy Hot Tub Water

The easiest way to prevent your hot tub water from foaming is to reduce the amount of oils, lotions, and soaps that you introduce into the water. The easiest way to do this is to have a quick shower before using the hot tub to remove most of the skincare products, makeup, deodorant or other personal care products that you might have on your skin. You can also greatly reduce the amount of laundry detergent and fabric softener that gets introduced to the water by washing your bathing suits separately using less detergent and giving them an extra rinse cycle before drying them. No matter how hard you try though, surfactants will slowly build up in the water. If your hot tub water is almost ready to change and starting to get a little foamy, regularly adding a small amount of anti-foaming chemicals to the water weekly can help eliminate the foam until it is time to refill the hot tub. Usually a good rule of thumb is empty the hot tub every 3-4 months unless otherwise specified by your tub manufacture.
