Your hot tub is foamy and sudsing as a result of several possible causes. If you notice foaming while you are enjoying your hot tub, one or more of these issues could be causing it:

  1. Laundry detergents from swim suits or clothes can cause foaming.

    That great smelling detergent comes out in the hot tub, and because the hot tub doesn’t drain like your bathtub, these outside elements often cause excessive foaming. A solution for this is to hand-wash or rinse your swimsuit after use in your hot tub
    instead of throwing it in the laundry.

  2. Deodorants, lotions, shampoos, perfumes, and other cosmetics can also leave a residue in the water that may make your hot tub foamy.
    Rinse off in the shower before going in your hot tub, or avoid using these kinds of items if you are planning to use your spa.
  3. Spilling drinks or food in your hot tub can cause foaming, not to mention other potential problems.
    It’s a good idea to use lids and to always use plastic drinkware to avoid injuries.
  4. Cheap chemicals often contain fillers that make hot tub water foamy.

Typically, buying cheap products from a general store instead from a trustworthy hot tub source (or using an excessive amount of chemicals) can causes foaming and sudsiness.

A high level of total dissolved solids (TDS), the combined content of inorganic and organic substances in the water, causes foaminess if not treated with something like SpaBoss.

No matter which of these causes is making your hot tub foamy, the best solution is to follow Master Spa instructions for maintenance and cleaning of your hot tub and filter,
and to use a small amount of SpaBoss Defoamer as instructed. This product can help reduce or remove foam in your spa.

To prevent foaminess from happening in the first place, follow Master Spa hot tub cleaning and maintenance directions. It’s recommended to drain and refill your spa every two to three months, and to replace the filter at least once a year. If you see foam in your hot tub, it is not harmful to yourself or your spa and there are easy ways to treat it and keep it from returning.

It’s time to enjoy your Master Spa hot tub foam free for many years to come!
