Why does my hot tub cover smell?

To keep your hot tub experience enjoyable, it’s important to address any unpleasant odours that might arise—especially from the cover. Here’s why your hot tub cover might stink and what you can do about it.

Why Does My Hot Tub Cover Smell?

Here are some common reasons for those odours:
  1. Algae Growth: If your cover gets a lot of sunlight, algae can start to grow on it, leaving behind a musty smell.
  2. Mold and Mildew: The warm, damp environment makes hot tub covers an easy target for mold and mildew, both of which can produce strong, musty odours.
  3. Bacteria Build-Up: Without regular cleaning, bacteria can accumulate and create a foul, sometimes rotten smell.
  4. Chemical Residue: The chemicals used to maintain hot tub water can sometimes leave residue on the cover, which can break down over time and cause odours.
  5. Animal Activity: Birds or small animals may occasionally leave waste on your cover, leading to an unpleasant smell.

How to Keep Your Hot Tub Cover Odour-Free

  1. Clean Regularly: Clean the cover at least once a week with mild soap and a soft brush to remove dirt, algae, and other grime. Rinse thoroughly.
  2. Ensure Proper Drying: Make sure the cover is completely dry before putting it back on the tub to prevent mould and bacteria growth.
  3. Use a Cover Lifter: A cover lifter helps keep water from sitting on top of the cover, which can prevent bacteria and mildew from growing.
  4. Store Correctly: When not in use, store your cover in a dry, well-ventilated spot to stop moisture from creating more problems.
  5. Add a Cover Protector: Consider using a cover protector as an extra shield against dirt, moisture, and other elements that could cause odours.

What to Do if the Odour Persists

If regular cleaning doesn’t fix the problem, you may need to try a commercial cleaner or disinfectant specifically for hot tub covers. If the smell is still there after that, it might be time to think about replacing your cover. By following these steps, you can help keep your hot tub cover fresh and odour-free, ensuring a better and more relaxing hot tub experience.
