Why does my hot tub feel slimy?

• <div><p>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. </p></div>

Can I use vinegar to clean hot tub filters?

• <div><p>Vinegar can be used as an all-purpose cleaner for many things, including hot tub filters. Soaking hot tub filters in vinegar and water for up to 24 hours can remove dirt and oil, and as a bonus, it won’t cause the water to foam after you reinstall it if there’s vinegar left on it. But make sure you still rinse it to remove any debris, dirt, or grime stuck on it.</p></div>

Q: Is green hot tub water safe?

• <div><p>Algae-related green hot tub water is generally safe to use, as algae aren't usually harmful to your health. However, if the conditions in the hot tub are hospitable to algae growth, they may also be hospitable to the growth of other types of microorganisms, including <i>Pseudomonas aeruginosa</i>, bacteria that can cause <a href="https://www.angi.com/articles/preventing-hot-tub-health-hazards.htm">hot tub rash</a>, or <i>Legionella</i> bacteria, which can cause respiratory illness.</p></div>

Q: What happens if you don’t prepare a hot tub for winter?

• <div><p>If water is left inside the hot tub pump over a cold winter, it could freeze and severely damage the pump, water lines, and jets. That can cause leaks, which require very expensive repairs. Freezing or leftover water can stain and damage the hot tub shell, which leads to replacement. Even in mild climates, leaving sitting water in the tub or pipes for a long period of unuse is a bad idea, since disinfecting chemicals fade and the water can develop bacteria, algae, and other big headaches when it&rsquo;s time to use the tub again.</p></div>

Q: What temperature do you keep a hot tub at when not in use?

• <div><p>You should keep your hot tub at a constant soaking temperature of around 100 degrees Fahrenheit when the hot tub is not in use. However, you can lower that by a couple of degrees during the summer, so you don&rsquo;t feel overheated.</p></div>
