Step #2: Remove All the Debris from the Tub

Gently scrub the affected areas to remove any buildup. Also, make sure to check the area if it is clean finally. Also, be extra careful not to damage the waterline by any means.

You can also put some cleaning powder chemicals inside it. The chemicals will dissolve all the dirt inside the deepest part of the pipe. But it can affect the quality of your tub water. So, be careful while choosing the right chemicals.

Step #5: Clean the Filters

As you know, the filters in your hot tub help remove impurities from the water. So, cleaning it is a must-have for you. However, you need to first remove the filters following the manufacturer’s instructions

Now, rinse the filters with a hose to remove all the noticeable dirt from them. If the filters are excessively dirty and full of oil content, you may need to soak them in a filter cleaner solution.

Step #6: Clean the Tub Body

If your hot tub is so dirty and the tub body is not clean as well, it’s time to give it a good wipe. You can use a sponge soak with a good quality hot tub surface cleaner and wipe all the areas of the tub.

You can also replace the cleaner with a disinfectant if you think there are fungi and bacteria all over it. If there is so much debris in the bottom, you can use a spa vacuum or a small submersible pump.

Make sure to follow the instructions provided with the vacuum or pump to effectively clean the bottom of the tub. Also, try to clean the headrest and the control panels of the tub properly.

Step #7: Treat the Tub Water

After cleaning, you should balance the water chemistry in your hot tub. For that, you need to treat the water. First, you have to use a water testing kit to measure pH, alkalinity, and sanitizer levels.

Next, you need to adjust the pH and alkalinity using appropriate chemicals. After that, add the recommended sanitizer, like chlorine or bromine to kill bacteria.

You might need to shock the water to get rid of contaminants and maintain clarity. For that, you can simply add a higher dose of hot tub chemicals to the water of the tub.

Besides, you can use a clarifier or flocculant to improve water clarity by removing all harmful particles.

Your hot tub must be clean now. At this point, it is suggested to drain the water as a lot of chemicals have been used in the water already. But if you don’t want it, you can leave it as it is.
