Would like to know if Epson salts & vinegar work as shock treatment in hot tub?
Hi this is Peggy. You will need to go by manufacturers recommendations . My son worked at a hot tub place and says you need some type of disenfectent to clean and "shock" the hot tub like chlorine . https://www.hunker.com/12597165/can-you-use-epsom-salts-in-a-hot-tub
Plain Water. Epsom salt is safe to use in a plain water hot tub. In order to avoid adding too much and causing possible corrosion to your tub's equipment, only add the manufacturer's recommended amount. For the full benefit, soak in the water for a full 30 minutes with the jets rotating the water.
Epsom salt and vinegar will CLEAN a hot tub, but to shock it you need something else...bleach. Here is an article...
The manufacturer has specific instructions for hot tubs-maintenance and cleaning. Follow them to the letter or you might void your warranty and damage your hot tub. If you have lost the booklet, give them a call with the make and model of your hottub, they have technical people to guide you.
