How to clean the inside of the hot tub shell

Cleaning the inside of your hot tub shell doesn’t have to be complicated. Follow these easy steps to keep your shell in excellent condition:

Step 1: Turn off the hot tub and drain the water

Before you begin cleaning, you’ll need to turn off your hot tub and drain the water to ensure that the cleaning process is effective.

1. Turn off the power: Switch off the hot tub’s power at the control panel to prevent any accidents during cleaning.
   

2. Drain the water: Use the drain valve or drainage hose to remove the water from the tub. Make sure to dispose of the water in an appropriate area.
   

3. Clean the filter: While the hot tub is draining, it’s a good idea to remove the filter and clean it as well. This will help prevent any debris from returning to the water once the tub is refilled.
   

Step 2: Prepare a cleaning solution

Once the hot tub is drained, it’s time to prepare a cleaning solution. You can use a store-bought hot tub cleaner or make a DIY solution using household ingredients.

• Store-bought cleaners: Many cleaning products are specifically designed for hot tubs. Look for one that’s suitable for your hot tub’s shell material (acrylic, fiberglass, etc.) and free of harsh chemicals that could damage the surface.
  

• DIY solution: If you prefer a natural alternative, you can mix equal parts of white vinegar and water in a spray bottle. Vinegar is a great natural cleaner that effectively removes grime, oils, and mineral deposits.
  

Step 3: Apply the cleaning solution

Now that you have your cleaning solution, it’s time to apply it to the inside of the hot tub shell.

1. Spray the solution: Spray the cleaning solution generously over the entire surface of the hot tub shell. Focus on any areas with visible stains or grime buildup.
   

2. Let it sit: Allow the cleaning solution to sit for 10 to 15 minutes. This will give it time to break down oils, dirt, and mineral deposits that have accumulated on the surface.
   

Step 4: Scrub the hot tub shell

After allowing the solution to sit, it’s time to scrub the inside of the shell to remove the dirt and stains.

1. Use a soft cloth or sponge: Use a soft cloth, sponge, or microfiber towel to scrub the surface. Avoid using abrasive materials that could scratch the hot tub shell.
   

2. Pay attention to the waterline: The waterline of the hot tub is where oils, lotions, and mineral deposits tend to accumulate. Be sure to scrub this area thoroughly.
   

3. Target stains: If you notice any stubborn stains, you may need to apply a bit more cleaning solution and let it sit for a few additional minutes before scrubbing.
   

4. Use a soft brush for corners and jets: If there are any tight corners or hard-to-reach areas, you can use a soft-bristled brush to get into those spaces. Gently scrub the jets and other parts of the hot tub shell.
   

Step 5: Rinse thoroughly

Once the inside of the hot tub shell is scrubbed clean, it’s time to rinse off the cleaning solution.

1. Rinse with clean water: Use a hose to rinse the inside of the shell thoroughly, ensuring all cleaning solution and residue are removed. If you’re using a garden hose, make sure the water pressure is moderate so as not to damage the shell
   

2. Check for leftover cleaner: As you rinse, make sure there is no cleaner left behind, as it can cause foam and affect water quality when the hot tub is refilled.
   

Step 6: Refill the hot tub

After cleaning and rinsing the shell, it’s time to refill the hot tub.

1. Check the water level: Fill the tub with clean water, ensuring it reaches the appropriate level for operation.
   

2. Inspect the filter: Before turning the hot tub back on, make sure the filter is properly reinstalled. If necessary, replace the filter if it’s worn out or damaged.
   

Step 7: Balance the water chemistry

Now that your hot tub is clean, it’s essential to balance the water chemistry before you enjoy your soak.

1. Test the water: Use a pool and spa water testing kit to check the levels of pH, alkalinity, and sanitizer. Make adjustments as needed to ensure the water is properly balanced.
   

2. Shock the water: It’s a good idea to shock the water after cleaning the shell. This will help remove any contaminants that may have been introduced during the cleaning process.
   

3. Add chemicals: Add any necessary chemicals to balance the water, such as chlorine, bromine, or pH adjusters.
   

Step 8: Turn the hot tub back on

Once everything is clean and balanced, turn the hot tub’s power back on and run the filtration system for a few hours to ensure the water is circulating properly.

How often should I clean the inside of my hot tub shell?

It’s recommended to clean the inside of your hot tub shell at least once every three to four months. However, if you use your hot tub frequently or notice that the water is getting cloudy or foamy, you may need to clean it more often.

Additionally, keep an eye on the waterline and other areas prone to buildup. If you see any signs of grime or stains, it’s a good idea to clean those spots immediately to prevent them from becoming harder to remove.
