How To Deal With Hot Tub Foam

Foamy hot tub water is caused by many things. One example is adding different products like drinks, soap, detergent, body oils, deodorant, and lotion to the water. Having low calcium levels in your tub can also cause foaming. Soft water can damage your tub, too, so check the hardness levels of your tub water. Here are the ways you can get rid of hot tub foam:


Getting Rid of Hot Tub Foam

The first thing you need to do is test the water because imbalanced water causes foaming. Check the alkalinity, pH, and sanitizer levels to know which products to add to balance the chemical levels. For a quick fix, you can also buy a high-quality foam remover. It will remove the foam almost instantly. However, this isn’t a good long-term solution as it can only last for up to 24 hours. It’s best to drain and clean your hot tub to get rid of the foam. Here are the steps in cleaning your hot tub:

  1. Use a line flush product, then remove the filters. It might be more expensive, but replacing the filters is the best option if they are dirty.

  2. Turn off your hot tub’s power, and drain the water using a sump pump or the drain plug.

  3. When your tub is drained, wipe it down using a hot tub cleaning solution or a mixture of white vinegar and water.

  4. Rinse the inside of your tub thoroughly to remove the cleaning solution.

  5. Replace your filters, then refill your hot tub.

  6. The last step is to test the water again, add chemicals, and allow it to circulate for at least a day.

Preventing Foamy Water

Prevention is the best course of action for foamy water. It’s easier and faster if you make sure to get the right chemical balance in the first place. Take a shower before soaking in your hot tub to remove all the dirt and products in your body like lotion, perfume, and deodorant. Make sure your bathing suit is rinsed as well to remove any detergent left in the material.
