How to Remove Hot Tub Odors

Does your hot tub cover stink? Smelly hot tub covers happen to most hot tub owners. There are easy ways to remedy the smell, but let’s first look at the common reasons as to why they even start.

Causes of Odors:

Low Quality Cover:

Not all hot tub covers are manufactured with the same materials and they differ in quality. If you own a low quality cover, you probably aren’t protecting yourself enough against mold and mildew. Low quality covers make it much easier for mold to grow on your hot tub and inside of the cover.

Cover isn’t Regularly Removed:

If your hot tub isn’t used very often, the spa cover is exposed to warm, humid water for longer periods of time. The more water that builds up, the more bacteria, mold and mildew grows.

Broken or Damaged Cover:

Cracks and holes in your hot tub cover trap moisture form rain or steam raising from warm hot tub water. These areas remain moist, providing an ideal environment from mold and mildew to flourish.

Bad, Untreated Water:

If you leave your hot tub water untreated, bacteria can grow in the hot tub water itself. Bacteria from the water is then turned into steam, which eventually winds up on the hot tub cover where the bacteria can further flourish causing icky smells.

The Cover is Dirty:

Outdoor hot tub covers are exposed to the elements constantly. Rain, wind, dirt and dust are constantly hounding it. Over time, the cover will become dirty. Dirt and grime combined with warm, humid temperatures create the ideal environment for mold and mildew to grow.

Remedy the Smell:

Now that we’ve covered the most common reasons for hot tub cover odors, let’s go over the ways to remedy the smelly issue.

Test & Balance the Water:

Test and balance your hot tub water at least twice a week. Healthy, properly balanced water greatly reduces the chance for mold and mildew to grow and flourish on your cover- thus greatly remedying any chances of smell causing bacteria to cause odors. Properly balanced water is key to a good smelling spa.

Remove & Clean the Cover:

Regardless of use, it is a good idea to remove the spa cover at least once a week for a few hours so it can dry and air out. While removed, you should use a hot tub cover cleaner to clean the inside and outside of the cover. Once cleaned, let the cover completely dry before replacing it on your hot tub.

Replace the Cover:

Sometimes it’s easier and possibly necessary to replace your spa cover. Inspect it- are there cracks or damage to the cover? If the answer is yes, it’s time to replace. Once you have a new cover, make sure to regularly test and balance your spa water and clean the cover out- allowing it to dry and air out.
