Many people find saltwater tubs worth the upfront expense. They cost less to maintain than traditional hot tubs, so you can save in the long term. Maintenance is also easier, typically involving balancing the pH and cleaning the tub rather than adding chemicals. They’re also gentler on sensitive skin, and you won’t walk away with a strong chlorine odor.

Biofilm growth can cause a hot tub to feel slimy. Hot tub biofilm is a slimy substance that’s typically due to natural contaminants like makeup, soaps, skin oils, deodorants, or lotions. A hot tub can also have a slimy interior or slimy water if the tub’s filters are old or damaged, or if the hot tub isn’t properly cleaned. You should drain your hot tub, wipe away any slimy residue, then refill the water and use a spa purge product that prevents the buildup of biofilm.

For a fully-foamed hot tub, freezing typically occurs when the temperature drops below 28 degrees Fahrenheit and remains at or below this level continuously for a minimum of 36 hours. If your hot tub and pumps are still operational, however, the water circulates, and this continuous movement helps prevent freezing, even in very cold conditions. This circulation, along with the insulation provided by the foam, helps maintain the water temperature and prevent it from freezing during extended cold periods. Still, if you’re not planning to run it regularly, be sure to winterize the hot tub properly to prevent damage from freezing.

The best thing with which to clean a hot tub is whatever the manufacturer recommends; in most cases, this is a gentle surface cleaner and a soft cloth. Recommended hot tub cleaners can include specially formulated cleaning agents, mild dish soap, baking soda, vinegar, or diluted bleach. For your hot tub exterior, choose wood or vinyl cleaner (depending on the casing material).

You should never use household cleaning products, harsh chemicals such as undiluted bleach or acids, or abrasive cleansers or cloths, as these can scratch or etch your hot tub’s coating or shell and cause permanent damage.
