When to Clean a Hot Tub?
Knowing when to clean a hot tub is just as important as knowing how to clean it. Regular maintenance and keen observation of your hot tub’s condition are key to keeping it in top shape.
Regular Maintenance Schedule
Establishing a hot tub maintenance schedule is the first step. Regular cleaning prevents the buildup of bacteria, mold, and mineral deposits, ensuring your hot tub is always ready for a relaxing soak. Here’s a simple schedule to follow:
- Hot tub surface cleaning: Once a week. This includes wiping down the shell and waterline to prevent scum buildup.
- Hot tub filter cleaning: Every two weeks. A clean filter ensures efficient water circulation and filtration.
- Hot tub draining and deep cleaning: Every three to four months. This includes hot tub line flushing, hot tub shell cleaning, and hot tub cover cleaning.
Remember, this is a general guideline. Depending on your hot tub usage and the quality of your water source, you may need to adjust this schedule.
Signs That Your Hot Tub Needs Cleaning
In addition to your regular cleaning schedule, you should also be on the lookout for signs that your hot tub needs cleaning. Here are some indicators:
- Cloudy water or foamy water: This could be a sign of high mineral content, imbalanced chemical levels, or a dirty filter.
- Unpleasant smell: A musty or chlorinated smell could indicate bacteria or algae buildup.
- Slimy or sticky surfaces: This is often a sign of bacterial growth.
- Poor water flow: This could mean your filter needs cleaning or replacement.
By keeping a regular hot tub cleaning schedule and paying attention to these signs, you ensure that your hot tub stays clean, safe, and enjoyable. So, don’t wait for your hot tub to scream for help. Be proactive and keep it clean!

Step-by-Step Guide to Cleaning a Hot Tub
Cleaning a hot tub might seem daunting, but with the right approach, it’s a breeze. Here’s a detailed, step-by-step guide to cleaning a hot tub.
Flushing the Hot Tub Lines
The first step in how to deep clean a hot tub is flushing the lines. Over time, biofilm – a slimy substance that harbors bacteria – can accumulate in the plumbing lines.
- Start by adding a line flush product to your hot tub water. Follow the instructions on the product label for the correct amount.
- Turn on your hot tub and let the jets run for about 15-20 minutes. This allows the line flush product to circulate through the plumbing and dislodge any biofilm.
- After running the jets, turn off the hot tub and proceed to the next step: hot tub draining.
Draining the Hot Tub
Draining your hot tub is a straightforward process, but it’s important to do it correctly to avoid damaging your tub or the surrounding area.
- Locate the drain valve on your hot tub. It’s usually at the base of the tub.
- Attach a garden hose to the drain valve and run the other end of the hose to a suitable drainage area.
- Open the drain valve and let the water flow out. This may take some time, so be patient.
- Once the tub is empty, close the drain valve.
Cleaning the Hot Tub Shell
With the hot tub drained, it’s time to clean the shell. This is where your hot tub cleaner and non-abrasive cloth or sponge come in handy.
- Apply the hot tub cleaner to the shell following the instructions on the product label.
- Use the cloth or sponge to wipe down the shell, paying extra attention to any areas with visible grime or scale.
- Rinse thoroughly with clean water to remove any residue from the cleaner.
Cleaning or Replacing the Hot Tub Filter
A clean filter is crucial for maintaining clear and water clean in your hot tub. Here’s how to clean or replace your filter.
- Remove the filter from its housing. The location and removal process may vary depending on your hot tub model, so refer to your owner’s manual if needed.
- Rinse the filter with a garden hose to remove any loose debris.
- If your filter is heavily soiled or hasn’t been replaced in a while, consider replacing it with a new one. If not, you can deep clean it using a filter cleaner. Follow the instructions on the product label for the correct usage.
- Once the filter is clean or a new one is ready, reinstall it in the filter housing.
Refilling the Hot Tub
With the hot tub and filter clean, it’s time to refill the tub.
- Remove the filter and fill the tub with water using a garden hose. The water level should be about halfway up the skimmer opening or as recommended by your hot tub manufacturer.
- Reinstall the filter.
Starting Up the Hot Tub
Now that your hot tub is clean and filled with fresh water, it’s time to start it up and balance the water chemistry.
- Turn on the hot tub and let the water circulate.
- Use your water test kit to check the water’s pH, alkalinity, and sanitizer levels.
- Adjust the water chemistry as needed using your hot tub chemicals. Always follow the instructions on the product labels for the correct usage.
Cleaning the Hot Tub Cover and Cabinet
The final step in your hot tub cleaning process is cleaning the cover and cabinet. These parts of your hot tub are often overlooked, but they need care too.
- Remove the cover and clean it with a mild soap and water solution or a product specifically designed for hot tub covers. Rinse thoroughly and let it dry.
- For the cabinet, wipe it down with a damp cloth. If your cabinet is made of wood, consider applying a wood cleaner or polish to keep it looking its best.
Congratulations! You’ve just completed a thorough cleaning of your hot tub. With regular maintenance and care, your hot tub will provide you with many years of relaxation and enjoyment. Happy soaking!

Hot Tub Maintenance Schedule
Maintaining a hot tub is all about consistency and simplicity. By breaking down the process into manageable steps, you can keep track of tasks without feeling overwhelmed. This technique, known as chunking, is widely used to improve productivity. It’s just as effective for planning a personal project, like a year’s worth of hot tub maintenance.
Every hot tub is different, but all benefit from simple and consistent maintenance. Setting up a schedule to keep your hot tub in top condition is easier than you might think.
Daily Hot Tub Maintenance
Daily maintenance only requires a few moments. Your daily checklist should include:
Ensuring the spa cover is clean and secure Checking the water temperature and adjusting as necessary Checking for damage to the cover and spa
Weekly Hot Tub Maintenance
Adding these tasks to your list three times a week will help keep your hot tub in top condition:
Checking the water’s alkalinity Checking and balancing the pH Checking your sanitizer levels Cleaning above the waterline
Weekly Tasks
These tasks need your attention only once a week:
Testing your hot tub wate Sanitizing and shocking the water Rinsing your hot tub filter with water Wiping down your spa cover
Monthly Tasks
Once a month, it’s time to get down to the nitty-gritty:
- Giving your filter a chemical rinse
- Checking your hot tub jets
- Having your spa water checked by a professional
Quarterly Tasks (Every 4 Months)
Once every three or four months, you should:
- Clean your hot tub cabinet
- Give your filter a chemical soak
- Drain, clean, and repair your hot tub
Yearly Tasks
While many tasks could, in theory, be done annually, for optimal performance we recommend them as monthly or quarterly tasks. However, these tasks should be tackled at least once a year:
- Flushing the lines to remove bacteria and biofilm
- Inspecting your hot tub’s hardware and wiring
- Having a professional perform a tune-up
- Inspecting your cover
- Replacing or updating your hot tub maintenance calendar
Remember, while your hot tub is empty and drained, you can attend to weekly or quarterly tasks such as cleaning, repair, and system flushing. As the years go by, you’ll learn what works best for you and your hot tub. The new year is the perfect time for adjustments to next year’s maintenance schedule.
Tips for Quick Hot Tub Cleaning
We get it – life is busy. Sometimes, you need a quick solution for cleaning a hot tub. While it’s important to perform a thorough cleaning regularly, there are times when a quick clean is all you can manage. Here are some tips for those moments.
Quick Cleaning Methods
- Surface Wipe Down: If you’re short on time, a quick wipe down of your hot tub’s interior surfaces can help keep it clean. Use a non-abrasive cloth or sponge and a mild cleaner to wipe away any visible dirt or grime.
- Filter Rinse: While a deep filter clean is ideal, a quick rinse can help remove surface debris and improve water flow. Simply remove the filter and rinse it with a garden hose.
- Chemical Check and Balance: Regularly checking and balancing your hot tub’s water chemistry is crucial. Use a water test kit to quickly check the pH, alkalinity, and sanitizer levels, and adjust as necessary.
- Shock Treatment: A shock treatment can quickly sanitize your hot tub water. It kills bacteria and breaks down contaminants, keeping your water fresh, clear and safe.
Precautions to Take
Even when you’re in a hurry, safety should never be compromised. Here are some precautions to keep in mind:
- Never Mix Chemicals: Mixing different harsh chemicals can lead to dangerous reactions. Always add chemicals separately and allow the water to circulate before adding another type of chemical.
- Don’t Overdo It: More is not always better when it comes to hot tub chemicals. Adding too much can lead to imbalanced water, which can damage your hot tub and irritate your skin and eyes.
- Keep the Cover On: When your hot tub is not in use, keep the cover on. This prevents debris from entering the tub and reduces the amount of cleaning required.
Remember, a quick clean is not a substitute for regular, thorough hot tub maintenance. But when you’re pressed for time, these tips can help keep your hot tub clean and enjoyable.
