Hot tubs are a wonderful place to relax, but they are also a breeding ground for bacteria. Bacteria grow in the warm water, but you can easily sanitize your hot tub to exterminate it. Harsh chemicals may make for an uncomfortable soaking experience, irritating the skin and drying out your hair. Using a sanitizer that is proven to kill bacteria while being gentle on the skin is important to keep your hot tub enjoyable year around.
Buy H2O2 hot tub cleaner or sanitizer from a pool and spa store. It may also be advertised as hydrogen peroxide cleaner.
Measure 1/4 to 1/2 cup of H2O2 cleaner into a cup for every 100 gallons of water your hot tub holds. Pour directly into the water for regular sanitizing.
Apply a maintenance dose of cleaner up to 10 minutes before getting into the tub. Pour in 1/8 cup of H2O2 cleaner per 100 gallons to ensure the hot tub doesn't become bacteria-laden while people are inside.
Perform regular sanitizing once a week if the water is not drained during that period. Perform maintenance immediately after getting out if the heater will be kept on while the tub is empty.
