- Yes. Natural Spa will work in inflatable hot tubs and hot tubs with vinyl liners. However, Natural Spa contains enzymes that are naturally attracted to the oils in your vinyl liner. This will cause the sides to become very slippery and become an inconvenience for you. A solution is to use a wash cloth to wipe the sides of the tub so the "slippery" film (Natural Spa) will dissolve back into the water every few days.
- Best Solution! - Use Mineral Spa rather than Natural Spa in a hot tub with a vinyl liner such as an inflatable tub. Mineral Spa does not contain enzymes so it will not cause the liner to get slippery. Mineral Spa Startup Kit
