How to Clean a Hot Tub with Natural Ingredients

Are you tired of using chemicals to clean your hot tub? Have you ever considered cleaning your hot tub with natural ingredients instead of harsh, corrosive, chemicals?

How to Clean a Hot Tub with Natural Ingredients

While we do believe that used properly these harsh chemicals can do a great job at keeping your hot tub clean and safe, sometimes they aren’t the right fit for you. For example, your skin could be sensitive to chlorine or other types of cleaners used to sanitize your hot tub. Your health may not have anything to do it. Instead you may want to use natural ingredients to be as environmentally friendly as you possibly can.

Whatever the reasons, knowing how to clean a hot tub with natural ingredients is key to reducing or maybe even eliminating your dependence on these chemicals once and for all.

Natural Sanitizers

You don’t have to stick with chlorine or bromine as sanitizers in your hot tub. There are other solutions that use natural ingredient to clean and sanitize your water.

Ultraviolet Radiation

We all have heard both the benefits and harmful side effects of ultraviolet radiation. UV sanitizers turn some these negatives into a positive when you think about it. Water in your hot tub is passed through a small chamber where it is exposed to powerful ultraviolet light.


Ozonators have risen in popularity in recent years and have become a great way of supplementing your chemical cleaners. These devices use ozone gas as a powerful sanitizer. During this process, ozone, which is 3000 times more powerful than chemicals, is injected into the water to clean it. The remaining ozone is then reabsorbed by the ozonator and then the process repeats itself resulting in clean water for you to enjoy.

This is a chemical-free option that kills microorganisms that can grow in your water by releasing copper and silver ions into the water. The water passes through an Ionization Unit where electrified silver and copper anodes are released into the water. These ions will kill bacteria and algae with relative ease, but won’t take care of other types of contaminates found in hot tub water.


Polyhexamthylene biguanide is a synthesized chemical but it differs from chlorine and bromine in many different ways. It is very easy on the skin and eyes and isn’t harmful to the environment. You can even find this chemical in some contact lens solutions. A more natural and less harmful solution, this chemical still requires the same levels of pH and alkalinity monitoring that you must do with chlorine.

Natural Cleaners

In addition to water sanitizers, you will need water cleaners and hot tub cleaners as well. These are often added to the water to break down organize material or used to clean the surfaces and fixtures of your hot tubs when you drain it for a thorough cleaning. You may need to regularly add water cleaner to the water in addition to using these sanitation methods.

When you drain your hot tub, instead of using abrasive cleaners filled with chemicals, instead try to use a cleaner made with natural enzymes to scrub the surfaces of your hot tub. Once you are finished, all you must do is rinse away the cleaner and you will have a hot tub that not only is clean, but one that also shines and is ready to be refilled and enjoyed.


Cloudy water is a problem that all hot tub owners face at one time or another. There are many chemical-based water clarifiers out there. While they work, they aren’t made from natural ingredients. Did you know that instead of a chemical clarifier, you can buy all natural clarifiers that will do just as good a job at clearing up your cloudy water? Just add these clarifiers to your water instead of the chemical clarifier and watch your water clear naturally the way nature intended.

Shock Treatment

Sometimes, you need to shock your hot tub to give the water a good cleaning. In most cases, you should do this periodically to maintain optimal water quality, but if you may need to do it more often if you have a heavy bather load one day or your hot tub is just getting used heavily. While there are tons of chlorine shocks out there, there are non-chlorine solutions as well made of potassium. Now these do generate some chemical compounds, but it is still technically a natural solution and should be used regularly by every hot tub owner.
