Preparing for Cleaning

Before you begin cleaning your hot tub, there are a few important steps to ensure a safe and effective process.

Power Off Hot Tub

First, power off your hot tub to prevent electrical accidents or damage. Locate the power switch near the hot tub and turn it off.

This will help keep you safe while cleaning and protect your hot tub equipment.

Check the Circuit Breaker

Next, head to the circuit breaker panel in your home or the one designated specifically for your hot tub. Double-check that the breaker corresponding to the hot tub is in the “off” position.

This extra step ensures no power is supplied to the hot tub while you clean it.

With these precautions in place, you are ready to proceed with cleaning. Remember to work carefully and methodically, and your hot tub will be sparkling clean.

How to Clean a Hot Tub – Step by Step

Drain the Water

Before cleaning your hot tub, you need to drain the water.

You can use a garden hose to drain the water by creating a siphon, opening the drain valve if your hot tub has one, using a submersible pump or using a wet/dry vacuum.

Inevitably, an inch of water will be left in the bottom, which you will have to remove manually. I normally use a small container and a sponge, which I empty into a bucket.

Once the water is drained, use clean rags and a spa shell cleaner to clean as necessary while the hot tub is empty.

Remove Debris and Grime

Before you start cleaning the spa shell, make sure to remove any debris or grime that might be present. You can use a soft cloth or sponge to wipe the interior surfaces of your hot tub gently. Don’t forget to wear gloves to protect your hands from any chemicals or residues that might be present.

Clean the Spa Shell

Now that you’ve removed debris and grime, it’s time to clean the spa shell! To clean your hot tub shell, use a mixture of equal parts distilled white vinegar and water or a product made specifically for spa acrylic shells. Such cleaners are available at your local hot tub dealer.

Spray the cleaning solution onto the shell, focusing on areas with obvious staining or buildup. Use a soft cloth to wipe the surface gently so as not to scratch the acrylic. Clean all hot tub parts, including the control panel, pillows, and skirt.

While cleaning the hot tub shell, make sure to:

  • Use a soft cloth: Avoid abrasive materials that could scratch or damage the acrylic.
  • Avoid harsh chemicals: Stick to vinegar and water or cleaners specifically designed for hot tubs.
  • Pay attention to detail: Don’t forget to clean around the jets and other hard-to-reach areas.

This step may vary depending on your hot tub model, so consult your user manual for specific instructions on removing the filters.

Clean Filters with a Solution

You can use household items like white vinegar or baking soda to create an effective cleaning solution.

  • White Vinegar Solution: Mix equal parts of white vinegar and water in a bucket or container large enough to accommodate the filter cartridges. Soak the filters for 2-4 hours, allowing the vinegar to break down and loosen the contaminants.
  • Baking Soda Solution: Dissolve about 1/4 cup of baking soda in warm water and pour it into a suitable container. Soak the filter cartridges for a similar duration as with the vinegar solution.

Remember not to use bleach or laundry detergents, which can damage your filters.

Alternatively, you can purchase a specialized filter cleaner like the one below.

Rinse and Replace Filters

Once the filters have soaked, use a garden hose to thoroughly rinse them, ensuring all cleaning solutions and debris are washed away.

Allow the filters to dry before reinstalling them in the hot tub. Maintaining this routine weekly or per your manufacturer’s recommendations is important.

Refill with Fresh Water

Now that the water is drained and the hot tub cleaned, it’s time to refill it with fresh water. Follow these steps:

  1. Fill the hot tub using a clean garden hose, ensuring the water flow isn’t obstructed.
  2. Check for leaks or issues with the hot tub as the water fills.
  3. Keep an eye on the level, as it is easy to overfill.

When the hot tub is full, turn the power back on and follow the manufacturer’s instructions on balancing the water’s chemistry and temperature.

Once the water is back up to temperature, it is ready to use!

Continuous usage of hot tub pillows can accumulate dirt, oil, and grime. To keep your hot tub experience enjoyable, follow these simple steps to clean hot tub pillows:

  1. Remove the pillows: Carefully detach the pillows from the hot tub.
  2. Prepare a gentle cleaning solution: Mix a mild detergent or soap with warm water.

Remember to clean your hot tub pillows at least every two to three months or more frequently if you use your hot tub often.

Maintain Control Panel

The control panel is an important component of your hot tub, so keeping it clean and functional is essential. Here’s how to maintain your hot tub’s control panel:

  1. Switch off the hot tub: Before you start, ensure the hot tub is turned off and disconnected from any power source.
  2. Wipe the surface: Gently clean the control panel using a soft, damp cloth.
  3. Clean the buttons: To remove any dirt buildup, use a cotton swab dipped in rubbing alcohol. Carefully clean around each button to avoid damaging the electronics.
  4. Inspect for any damages: Regularly check for any signs of wear, corrosion, or damage, and seek professional help if necessary.

Following these steps, you can ensure your hot tub controls remain functional and easy to use.

Maintaining Hot Tub Components

Clean the Jets and Pipes

To maintain the longevity of your hot tub, it’s essential to clean the jets and pipes regularly.

Start by adding a hot tub cleaner or line flush product to the water, following the manufacturer’s instructions. This will help break down any built-up grime and contaminants within the jets and pipes.

Keep an Optimal Water Temperature

Maintaining an optimal water temperature is critical for your hot tub’s performance and energy efficiency. Typically, the ideal temperature range for a hot tub is between 100°F to 104°F (38°C to 40°C).

However, you may need to adjust the temperature depending on your comfort level, location, and climate.

To keep your hot tub’s temperature consistent:

  • Regularly check the water temperature and adjust accordingly.
  • Use a high-quality, well-insulated cover to minimize heat loss.
  • Monitor and adjust your hot tub’s filtration and circulation settings as necessary.
  • Keep an eye on the water level and top it off as required.

Regular Maintenance and Cleaning Schedule

Perform Weekly Checks

To keep your hot tub clean and maintain an enjoyable experience, it’s essential to establish a regular maintenance and cleaning schedule. By performing these tasks weekly, you’ll help prevent the buildup of debris, bacteria, mold, and mildew.

Every week, you should:

  • Check and adjust water chemistry: Test your hot tub’s chemical levels, such as sanitizer (chlorine or bromine), pH, total alkalinity, and calcium hardness. Adjust them to keep everything within the recommended range for a comfortable and safe hot tub experience.
  • Remove debris: Use a skimmer or a spa vacuum to remove leaves, dirt, and other contaminants from your hot tub’s water. This will help maintain your jacuzzi’s cleanliness and reduce the chances of developing biofilm.
  • Wipe down surfaces: Regularly cleaning the exposed surfaces of your hot tub using a spa-friendly cleaner can help prevent the buildup of grime and bacteria. Pay close attention to the waterline, where residue can accumulate over time.

Deep Clean Quarterly

In addition to your weekly maintenance checks, it’s crucial to deep clean your hot tub every quarter. This involves:

  • Draining and refilling: Fully drain the water from your hot tub to provide access to areas that are more difficult to reach during your weekly cleaning. Thoroughly clean your hot tub’s interior and exterior, paying special attention to the spa shell, which may gather buildup over time.
  • Clean or replace filters: Inspect the hot tub’s cartridge filters and either clean or replace them if necessary. Properly functioning filters will help keep your water circulation system in good condition and ensure it can effectively remove unwanted substances from the water.
  • Sanitize the plumbing: To overcome biofilm buildup within the hot tub’s plumbing system, it’s a good idea to use a plumbing cleaner to flush out any bacteria and debris hiding in the pipes.

By following this routine maintenance and cleaning schedule, you’ll be able to keep your hot tub running efficiently and enjoy a clean, relaxing space for years to come.


Cleaning a hot tub involves several steps: turning off the power, draining the water, removing debris, and cleaning the shell with a gentle solution. Regularly clean and replace filter cartridges and refill with fresh water. Maintain accessories like pillows and control panels, and keep water at an optimal temperature. Regular maintenance ensures safety and enjoyment.
