While the warm temperature and bubbles are usually welcome features in a hot tub, there’s one thing that you don’t want to experience with your water – foam. It’s hard to sit back and relax in your hot tub when you notice a mysterious foam floating on top of the water.  But the good news is that you aren’t stuck with it. There are steps you can take to deal with this hot tub foam and prevent it from coming back. 

In this blog post, we’ll discuss the causes of hot tub foam and provide you with some practical tips on how to deal with it effectively.

What Causes Hot Tub Foam?

Before we dive into how to deal with hot tub foam, it’s important to understand what causes it in the first place. There are several factors that can contribute to foamy water in your hot tub, including: 

  • Body oils and sweat
  • Personal care products, like lotions and makeup
  • A chemical imbalance in the water
  • Crumbs and spills from food and drinks

As you can see, it’s hard to completely avoid some of these factors, especially something like body oils and sweat. Fortunately, though, there are some things you can do to help minimize their impact.

Tips for Dealing with Hot Tub Foam

Ready to make hot tub foam a thing of the past? Try the strategies below to get back to a foam-free experience.

Test and Balance Your Water Chemistry

Since a chemical imbalance is one of the most common causes of hot tub foam, the first thing you should do is ensure that your water chemistry is properly balanced. This means testing the pH levels, sanitizer levels, alkalinity, and calcium hardness in your hot tub water, and adjusting them as needed to maintain a clean and healthy environment for your hot tub.

Shock Treating Your Hot Tub Water

If you’re still dealing with hot tub foam after balancing your water chemistry, it may be time to shock treat your water. For those who haven’t done it before, shock treatment involves adding a large dose of sanitizer to your hot tub water to kill off any bacteria or contaminants. They could very well be the main cause of your foam. 

Since all products are different, be sure to carefully follow the instructions on your shock treatment of choice, and allow time for the sanitizer to work its magic.

Drain, Clean, and Refill

Finally, if the previous two strategies aren’t getting you anywhere, then you’ll likely need to drain, clean, and refill your hot tub to ensure a foam-free experience. Yes, it will be a little more work, but it really is the best way to address all of the different potential causes. Besides, you can always hire a hot tub service to take the job off of your hands. 

How to Prevent Hot Tub Foam

Once you’ve successfully dealt with hot tub foam, you’ll likely want to prevent it from coming back anytime soon. Here are some tips on preventing future hot tub foam:

  • Shower before entering your hot tub to reduce the amount of oils and contaminants introduced into the water
  • Avoid using excessive amounts of lotions, makeup, or oils while soaking in your hot tub
  • Regularly maintain your water chemistry and clean your filters

The Bottom Line

There’s no doubt that dealing with hot tub foam can be a frustrating experience for many hot tub owners. But by understanding its causes and taking proactive steps to address them, you can enjoy clear and clean water in your spa once again. 

Here’s to a foam-free hot tub experience!
