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>

Where should you drain a hot tub?

• <div><p>Where you drain a hot tub largely depends on local regulations, but you must not drain chemically treated water where it can damage the environment. Direct the water toward a sanitary sewer drain that will take it to a treatment facility. If your lawn has a dedicated drainage area that’s free from plants and foundations, you can likely drain it there. Avoid storm drains, as the hot tub water will enter waterways and could hurt aquatic life. Likewise, do not pour it out directly on any public land or where it can get into your neighbors’ property. </p></div>

Q: How often do you need to change the water in a swim spa?

• <div><p>How often you change the water in your swim spa depends on how often you use it. Most manufacturers recommend changing the water every three to six months. If you use your swim spa throughout the seasons, it&rsquo;s a good idea to set up a quarterly deep cleaning schedule. The ideal instructions should be in the owner&rsquo;s manual.</p></div>

Q: Is it OK to clean a hot tub with vinegar?

• <div><p>In most cases, it is safe to clean a hot tub with vinegar. You will want to verify that your hot tub manufacturer lists vinegar as a safe cleaning product; however, given that vinegar is chemical-free, cleans, deodorizes, and is safe for people and pets, it is usually a good option. You can use vinegar to clean the hot tub shell, interior and exterior spa surfaces, hot tub jets, hot tub filter, and other parts. It is considered a strong, safe, and natural cleanser that can kill bacteria, remove mold and mildew spores, erase water spots, and remove hard water stains.</p></div>

Q: Can you repair a hot tub yourself?

• <div><p>Whether you can repair a hot tub depends on the severity of the problem and the location. With the right tools and knowledge, you can fix problems like small leaks or switching out a dirty filter. However, electrical and plumbing issues require a licensed professional due to the inherent risk, particularly when mixing water with electricity.</p></div>

Heavenly Heat Infrared Saunas are made for the chemically sensitive. That means that our infrared saunas create an ideal, safe, and effective detoxification environment for anyone seeking to eliminate toxic substances from their body.

"Terrible! Wish I had gone with another company. Here is the issue with Heavenly Heat. If your sauna arrives damaged or and issue arrives -- they have zero technical support. Your repairs will be done by any "joe" that heavenly heat finds to do the repair in your area. They will have no experience with Sauna's and are given no instructions regarding the chemical free aspect of these sauna's. The worst part is the buyer, me, was treated as if I was the problem for wanting my sauna repaired correctly. I would have refused the delivery had I realized I was receiving a damaged sauna and would have to spend hours and days trying to get this resolved. The owner, Bob Morgan, is extremely responsive before he has your money but after, is a different story. When inquiring about the sauna he would respond generally within 10 minutes. After you purchase, and particularly if you have a problem with it, you are treated as if you're a nuisance. My sister bought a competitors sauna around the same time and the service she received from knowledgable representatives was a world of difference from my experience. My other issue was that there were shipping delays and Bob would never communicate them. I would have to pursue him to get information. I think they make a decent sauna but I would not recommend for reasons stated above."
