How to Fix the Foam in a Hot Tub
- 1). Add commercial defoamer to your hot tub. Start with just a half teaspoon---or a cap-full---and wait a few minutes to see if it gets rid of the foam. If not, add a bit more. This will temporarily solve the problem.
- 2). Drain the hot tub.
- 3). Clean the hot tub with a scrub brush. You want to take care to clean off any dead skin or other debris that may be in the hot tub.
- 4). Refill the hot tub and add the proper chemicals.
- 5). Ask all who enter the hot tub to take a quick shower before getting in. It's easiest if you have a shower close to the hot tub. It doesn't need to be a full shower---just a quick rinse-off with water.
