Owning a hot tub is a wonderful way to relax and unwind after a long day. But to keep your spa inviting and safe, regular maintenance is essential. One of the most important tasks is draining and cleaning your hot tub. This process ensures your water stays fresh, your equipment runs smoothly, and your spa remains a healthy environment for you and your guests. In this post, I’ll walk you through the spa cleaning procedure step-by-step, sharing tips and tricks to make it easy and effective.


Why Regular Spa Cleaning Procedure Matters


Keeping your hot tub clean is about more than just aesthetics. Over time, dirt, oils, and chemicals build up in the water and on the surfaces. This can lead to cloudy water, unpleasant odors, and even damage to your hot tub’s components. Regular cleaning helps:


  • Prevent bacteria and algae growth

  • Maintain balanced water chemistry

  • Extend the life of your hot tub’s equipment

  • Improve your overall spa experience


If you want your hot tub to stay in top shape, a thorough cleaning every few months is a must. This includes draining the water completely and giving the tub a good scrub.

Step-by-Step Spa Cleaning Procedure: Draining Your Hot Tub


Draining your hot tub might sound intimidating, but it’s straightforward when you follow these steps:


  1. Turn off the power - Safety first. Switch off the power to your hot tub at the breaker to avoid any electrical hazards.

  2. Attach a hose to the drain valve - Most hot tubs have a drain valve near the bottom. Connect a garden hose to it to direct the water away from your home and landscaping.

  3. Open the drain valve - Let the water flow out completely. This can take 30 minutes to an hour depending on your tub size.

  4. Remove the filter - While the tub is draining, take out the filter(s) and set them aside for cleaning.

  5. Check for any remaining water - Use a wet/dry vacuum or towels to remove any leftover water in the bottom corners.


Draining your hot tub fully is the first step in a thorough cleaning. It allows you to reach all surfaces and remove any buildup that water alone can’t wash away.


How to Clean a Hot Tub After You Drain It?


Once your hot tub is empty, it’s time to clean the shell and components. Here’s how I do it:


  • Use a non-abrasive cleaner - Choose a cleaner specifically designed for hot tubs or a mild dish soap diluted in water. Avoid harsh chemicals that can damage the surface.

  • Scrub the interior - Use a soft cloth or sponge to scrub the walls, seats, and floor. Pay special attention to waterlines where oils and minerals collect.

  • Clean the jets - Jets can trap dirt and debris. Use a small brush or toothbrush to clean inside and around them.

  • Rinse thoroughly - After scrubbing, rinse the entire tub with clean water to remove any soap residue.

  • Clean the filters - Rinse your filters with a hose, then soak them in a filter cleaner solution if needed. Let them dry completely before reinstalling.


This cleaning step refreshes your hot tub and prepares it for fresh water and chemicals.

Refilling and Balancing Your Hot Tub Water


After cleaning, it’s time to refill your hot tub with fresh water. Follow these tips for the best results:


  • Use a hose with a filter - If possible, use a hose filter to reduce minerals and contaminants in your water.

  • Fill slowly - Fill the tub slowly to avoid splashing and to allow air to escape from jets and plumbing.

  • Turn the power back on - Once filled, restore power and turn on the jets to circulate the water.

  • Test and balance the water - Use test strips or a test kit to check pH, alkalinity, and sanitizer levels. Adjust as needed to keep your water safe and comfortable.


Balancing your water chemistry is crucial to prevent corrosion, scaling, and bacterial growth.


Tips for Maintaining Your Hot Tub Between Cleanings


Keeping your hot tub clean doesn’t stop after a deep clean. Here are some simple habits to maintain water quality:


  • Test water weekly - Regular testing helps you catch imbalances early.

  • Shock the water - Use a shock treatment weekly or after heavy use to break down contaminants.

  • Clean filters monthly - Rinse and soak filters regularly to keep them working well.

  • Cover your hot tub - Use a quality cover to keep debris out and maintain temperature.

  • Encourage showering before use - This reduces oils and dirt entering the water.


By following these tips, you’ll extend the time between full drain and clean cycles.
