How to Handle Mold and Mildew in Your Hot Tub

Dealing with mold and mildew in a hot tub can be frustrating and unsanitary. These unwanted intruders thrive in warm, damp environments and can lead to unpleasant odors, slimy surfaces, and even potential health concerns. Here’s how you can address and prevent mold and mildew in your spa.

What Causes Mold and Mildew in Hot Tubs?

Mold and mildew often grow in hot tubs due to poor maintenance, imbalanced water chemistry, or inadequate cleaning. The combination of heat, moisture, and organic matter creates the perfect environment for their growth. Neglecting to clean hard-to-reach areas, like jets and filters, can also contribute to the problem.

Signs of Mold and Mildew in Your Hot Tub

Not sure if your hot tub has mold or mildew? Look for these common signs:

  • Discolored spots or patches (black, green, or white).
  • Unpleasant, musty odors.
  • Slime or residue on surfaces like seats and walls.
  • Cloudy or dirty water.

How to Remove Mold and Mildew from Your Hot Tub

If you’ve discovered mold or mildew in your hot tub, follow these steps to clean it effectively:

  1. Drain the Hot Tub: Turn off the power and drain the water completely to access the affected areas.
  2. Clean Surfaces: Use a spa-safe cleaner and a soft brush or sponge to scrub the interior surfaces, including seats, walls, and jets.
  3. Disinfect the Tub: Mix a solution of water and diluted bleach (1 part bleach to 10 parts water) to disinfect areas with visible mold or mildew. Rinse thoroughly to remove any residue.
  4. Clean or Replace the Filter: A dirty filter can harbor mold and mildew spores. Clean it with a filter cleaner or replace it if necessary.
  5. Refill and Balance the Water: Refill your hot tub with clean water and test the chemistry. Adjust pH, alkalinity, and sanitizer levels to recommended ranges.

Preventing Mold and Mildew in Your Hot Tub

Regular maintenance is key to preventing future issues. Here are some tips to keep your spa clean and healthy:

  • Sanitize Regularly: Maintain proper chlorine or bromine levels to keep the water clean.
  • Clean Filters Monthly: Regularly clean your filters to remove trapped debris and organic material.
  • Keep the Cover Dry: Dry your spa cover after each use and leave it off occasionally to prevent trapped moisture.
  • Shock Your Hot Tub: Shock treatments help eliminate organic contaminants and bacteria, reducing the risk of mold and mildew.
