Review: Hot and clean - I purchased this Hot Tub Defoamer for my spa and it works extremely well. A small amount goes a long way and it removes foam almost instantly without leaving behind any weird residue or strong chemical smell. Before using this, my hot tub would get foamy pretty quickly after multiple people used it, especially with lotions or soaps in the water. After adding this defoamer, the water looked clean and clear again within seconds. It made the whole spa experience much more enjoyable. I also like that it works fast without affecting the water quality or irritating skin. The bottle lasts a long time because you only need a little bit each use. Definitely recommend this product if you want to keep your hot tub, spa, or fountain looking clean and foam free.
