A hot tub is a fantastic way to unwind and enjoy hydrotherapy, but keeping it clean is essential for safety and longevity. Studies show that improperly maintained hot tubs can harbor bacteria like Legionella, which can cause respiratory infections. In fact, nearly one-third of waterborne disease outbreaks in the U.S. are linked to poorly maintained hot tubs. To keep your hot tub safe and enjoyable, follow this step-by-step guide to proper cleaning and maintenance.
12 Steps to Deep Clean Your Hot Tub
As the most reputable hot tub store in Colorado Springs, we’ve outlined the essential steps for deep cleaning a hot tub:
1. Flush Out and Turn Off
Before cleaning, flush out the internal plumbing to remove bacteria, mold, and biofilm buildup.
- Use a specialized hot tub cleaner designed for flushing pipes.
- Pour it into the water and run the jets for 15–20 minutes to break down any buildup.
- Turn off the power at the circuit breaker to avoid electrical hazards.
2. Drain Your Hot Tub
Draining your hot tub completely is crucial before deep cleaning.
- Locate the drain plug near the base.
- Attach a garden hose to direct water away from your home.
- Use a wet-dry vacuum to remove any remaining water.
- Drain and clean your tub every 3–4 months or more frequently with heavy use.
3. Apply Hot Tub Cleaner
Once drained, clean the tub’s surfaces thoroughly.
- Use a non-abrasive hot tub cleaner and a soft sponge or cloth.
- Focus on the waterline where most buildup occurs.
- Rinse thoroughly with clean water to remove any residue.
4. Remove and Clean Filters
Filters trap dirt, debris, and bacteria, making regular cleaning essential.
- Remove the filter cartridges.
- Rinse them with a hose to remove large debris.
- Soak in a filter cleaning solution for at least 1–2 hours (overnight for deep cleaning).
- Allow filters to dry completely before reinstalling.
5. Clean the Cover
Your hot tub cover collects dust, dirt, and mold.
- Wipe it down with a mild soap solution and rinse well.
- Apply a UV-resistant cleaner to prevent fading and cracking.
- Let the cover dry completely before placing it back.
6. Refill Your Hot Tub
Once clean, refill your hot tub with fresh water.
- Use a hose filter to remove impurities.
- Fill the tub to the recommended level (just above the jets).
- Using filtered water reduces the need for excessive chemical treatments.
7. Turn the Power On and Add Cleaning Chemicals
After refilling, turn the power back on and allow the water to circulate.
- Add a sanitizer such as bromine or chlorine, following manufacturer guidelines.
- Run the jets for about 20 minutes to distribute the chemicals evenly.
8. Balance Water Chemicals Regularly
Testing and balancing water chemistry prevents cloudiness and bacteria growth.
- Use test strips or a digital tester to check pH, alkalinity, and sanitizer levels.
- Maintain a pH between 7.2–7.8 and an alkalinity level of 80–120 ppm.
- Adjust chemicals as needed to keep the water clear and safe.
9. Shock Your Hot Tub Regularly
Shocking eliminates bacteria, oils, and organic contaminants.
- Use a non-chlorine shock for bromine systems or chlorine shock for chlorine-based tubs.
- Add shock treatment once a week or after heavy use.
- Run jets for 20 minutes and leave the cover off for at least an hour to allow gases to escape.
10. Clean Your Filter Regularly
In addition to deep cleaning, rinse filters weekly.
- Remove and rinse with a hose.
- Avoid household detergents, as they cause foaming in the water.
- Replace filters when they show signs of wear.
11. Maintain the Water Level
Keeping the water at the proper level ensures optimal filtration and jet performance.
- Check the water level weekly.
- Refill as needed to prevent pump and heater damage.
12. Use a Cover When Not in Use
Keeping the cover on helps maintain cleanliness and temperature.
- Prevents leaves, insects, and debris from falling in.
- Retains heat, reducing energy costs.
- Protects the tub from UV exposure and harsh weather.
Final Thoughts
A clean hot tub provides a safe and relaxing experience. Regular maintenance, including draining and cleaning every few months and balancing water chemicals weekly, is key. Keeping the cover on when not in use helps maintain both cleanliness and energy efficiency.
