What Causes Foam in Hot Tubs?
Foam in hot tubs can be caused by various factors, and addressing these can help maintain a clean and enjoyable experience.
- Body Oils and Lotions: Natural oils from the skin, as well as lotions and soaps, can lead to foam formation in hot tubs. These substances can accumulate in the water, reacting with the sanitizer and creating bubbles that result in foam.
