Consistent hot tub care is crucial to keep the water clean, safe, and enjoyable. Neglecting proper maintenance can lead to cloudy water, bacterial growth, and equipment damage. But how often should you give your hot tub a thorough clean? The answer depends on factors like frequency of use, environmental exposure, and water chemistry.
A structured hot tub cleaning routine prevents buildup, extends equipment lifespan, and ensures a hassle-free soaking experience. Below is a breakdown of how often different maintenance tasks should be performed.
Daily Maintenance: Keeping Your Water Fresh
While you don’t need to do a deep clean daily, small maintenance tasks can significantly prevent long-term issues. Doing these simple steps will help keep your water clean and balanced:
Check the water temperature – Ensure your heater and thermostat are functioning properly.
Inspect water clarity – If the water looks cloudy or foamy, chemical adjustments may be needed.
Remove debris – Use a skimmer or net to clear out leaves, bugs, or dirt that may have fallen into the water.
These daily checks take just a few minutes but go a long way in preventing water contamination.
Weekly Hot Tub Cleaning Routine
Once a week, a more thorough cleaning routine is necessary to keep the water fresh and safe from contaminants. This includes:
- Test and adjust water chemistry – Use test strips to check pH (7.2–7.8), alkalinity (80–120 ppm), and sanitizer levels. Adjust as needed.
- Wipe the waterline – Remove any buildup from body oils, lotions, or other residues.
- Shock the water – A chlorine or non-chlorine shock treatment eliminates bacteria and organic matter, keeping the water clear.
If your hot tub is frequently used, consider increasing chemical testing to twice weekly to maintain proper balance.
Monthly Hot Tub Filter Cleaning
Filters play a vital role in trapping dirt and debris. A clogged filter reduces water flow and strains the pump.
- Clean the filter every month using these steps:
- Remove and rinse with a hose to clear loose debris.
- Soak in a filter cleaner solution to break down oils and grime.
- Make sure to rinse well and let it dry before putting it back in.
For hot tubs used heavily, cleaning the filter every two weeks may be beneficial. Additionally, filters should be replaced every 12 to 18 months for optimal performance.
Quarterly Deep Cleaning: Draining and Refilling
Even with proper care, hot tub water accumulates contaminants over time. Draining and refilling every three to four months helps maintain water quality and prevents chemical imbalances.
Follow these steps for a thorough clean:
- Flush the plumbing – Use a specialized cleaner to clear buildup in pipes.
- Drain completely – A submersible pump speeds up the process.
- Scrub the shell – Use a non-abrasive cleaner to wipe down surfaces.
- Rinse, refill, and rebalance – Ensure no cleaner residue remains before refilling.
Draining may be needed more often if debris accumulates quickly or the tub is used frequently.
Seasonal Considerations for Hot Tub Cleaning
Different seasons bring unique challenges for hot tub maintenance.
- Winter – If you use your hot tub in colder months, regular maintenance is crucial to prevent freezing and damage to the pump and pipes. Keeping a well-insulated cover on when not in use helps retain heat and keep out debris.
- Summer – Warmer temperatures can lead to increased algae growth and bacteria buildup. Test and adjust chemicals more frequently to maintain clean water.
- Low Usage – If your hot tub is used infrequently, you may not need to test and balance the water as often. However, occasional shocks and filter cleanings are still necessary.
Signs Your Hot Tub Needs Immediate Cleaning
Even with a regular schedule, your hot tub may need extra attention. Watch out for these warning signs:
- Cloudy or foamy water – Indicates chemical imbalance or excessive contaminants.
- A strong chemical or musty odour – Suggests bacteria growth or overuse of sanitizers.
- Sticky or slimy surfaces – A sign of biofilm buildup that requires immediate scrubbing and shocking.
- Reduced water circulation – May indicate a clogged filter that needs cleaning or replacement.
Addressing these issues quickly prevents further damage and ensures a safe soaking experience.
Final Thoughts
Maintaining a clean hot tub doesn’t have to be difficult when you follow a regular routine. Daily upkeep, weekly chemical balancing, monthly filter maintenance, and seasonal deep cleans all contribute to keeping your water safe and enjoyable.
By following these hot tub cleaning guidelines, you can extend the longevity of your spa, avoid costly repairs, and enjoy crystal-clear water every time you soak.
