Best Water Softener Cleaner – Complete Buyer’s Guide

When it comes to choosing a water softener cleaner, it is important to consider a number of different factors to ensure that you are buying the right one for your needs. There are so many different types of water softener cleaners out there that it can be hard to know what exactly you should go for.

Luckily for you, we are experts, and we have decided to put our years of experience to use and let you know exactly what to look for when you are buying a water softener cleaner. In this section of the article we have broken down the buying process into a number of different factors that you should consider before purchasing a cleaner. Think of it as your own personal Buyers’ Guide.


Compatibility – it is probably the most important consideration to make! You really need to make sure that the cleaner that you purchase is compatible with your particular brand of softener system. Take some of the examples on our list – many are ‘universal’ meaning they are compatible with almost every brand (make sure to check just in case).

Whereas other products on our list are only compatible with their specific brand – the Kenmore product for example should only be used with Kenmore systems. An incompatible product could mean that it will be an ineffective waste of money at best, or could damage your system beyond repair at worst. With all this in mind, we are sure you can agree with us about the importance of ensuring compatibility between them.

Easy to Pour

Most of the time, the water softener cleaners are not as easy to pour down into the softeners with efficiency. That’s because they are stored in bottles that are either difficult to handle like some of the huge ones on this list, or are not ergonomic. That is not to say that all big bottles will be difficult to pour.

As long as you ensure there are handles and easy pour spouts or caps then the bigger bottles should not be an issue. Likewise, if you have a powdered cleaning solution, then you should ensure you can easily decant the amount of powder needed from the container and not have any spillages. 

Advanced Cleaning Technologies

The whole point of investing in a water softener cleaner is that it should clean the softener thoroughly. The efficiency of a water softener system can be minimized due to the rust stains that might be there along with contaminations and buildup.

To avoid these problems within your softener system you will need to purchase a water softener cleaner that has got advanced cleaning technologies, proven to cut through all of this build up, dispersing any rust and iron, and helping to prevent future build ups from happening. 

Consider what sort of cleaner you need 

By this we mean that you need to think about the main problems affecting your water softener system. Do you suffer from metallic tasting or smelling water supplies? Perhaps it smells like sulfur?

Identify whether there is a rust or iron build up or whether the problem is related to mold and bacteria build up. This will then dictate what sort of cleaner you buy. Whilst most cleaners will disperse bacteria and mold, not all of them are as effective against rust, so if your rust issue is particularly prominent you should choose a rust specific cleaner like some that we have listed above. 

Go for an Odorless Water Softener Cleaner

This is also important. You need to buy a water softener cleaner that offers odorless cleaning, or at least, as odorless as possible. Just think, this cleaner is going to be inside your water softener tank – the same water softener tank provides tap water, shower water, laundry water and dish water. Ensure it is not going to leave nasty smells (and tastes!) behind.

Advantages And Disadvantages Of Using A Water Softener Cleaner

Now that you know all about the best water softener cleaners on the market, and know exactly what to look for when you are purchasing one for yourself, you may well be wondering whether it is worth buying one. (Spoiler alert: the answer is yes). We have decided to tell you all about the advantages and disadvantages of using a water softener cleaner to help you decide for yourself if it’s worth it. 


  • In our opinion, the advantages of using a water softener cleaner are glaringly obvious. I mean, who wouldn’t want a safe supply of water for use in their home? Having a clean water supply means that you don’t have to worry about contamination from organic compounds, iron, rust, and debris. Your water will be soft, safe for cooking with, and will not stain your appliances.

  • It can stop the build up of scales and unsightly stains. Having hard water can cause scales on the inside of appliances such as your washing machine, dishwasher, and even your kettle and water dispensers. You may think that having a water softener system automatically stops this…and it is – provided it is clean and in full working order. To ensure it is clean and in full working order you need to use a water softener cleaner. This ensures the system can still do its job and provide you with soft water that will not damage your appliances.

  • Your water pressure may improve. Having a build up in your water softener system can cause issues such as low water pressure. You know that feeling when you are in the shower and it’s just trickling out, and nothing you seem to do will make the water come out faster? Well, that is a result of low water pressure. The build up in your water softener system blocks the pressure. However, using a cleaner can fix this issue for you. 

  • Using a water softener cleaner can also help you to have softer laundry. Yes, you read that correctly! Having hard water can cause laundry to be rough and stuff. The water softener cleaner removes scales and builds up, ensuring it can provide you with soft water again. This has a knock-on effect for all of your appliances, and you will certainly notice a difference with your freshly laundered clothes, sheets and towels. 
  • Using a water softener cleaner could potentially reduce plumbing costs. This is because you will be maintaining your water softener system, and in turn, will be helping to ensure lots of hard water does not begin to damage your internal water pipes and systems. Soft water can prevent harmful build ups of scale and rust throughout your home, and so it is well worth ensuring your water softener system is kept clean, right? 


  • Sadly, there are some disadvantages of using a water softener cleaner, and they mostly revolve around the fact that the cleaners are chemicals or corrosives. This could potentially be harmful to our health.
  •  For example, you should not use these cleaners without protecting your clothes and skin. 
  • Due care should always be taken when handling liquids in case of spillages that could burn the skin. Powdered cleaners have the potential to irritate your eyes, skin and lungs so you should consider wearing a mask when using them. 
  • The cleaners can be toxic if ingested. For this reason it is absolutely essential that you follow the individual instructions on each cleaner before using it to ensure that none of the cleaners will be present in your water when you use it. This may involve flushing it out or running the generator manually. 

Frequently Asked Questions for Water Softener Cleaners

What can I use to clean my water softener?

As you can probably imagine by now after reading this whole article, we truly believe that the best way to clean your water softener is to purchase a water softener cleaning product. Sure, there are probably lots of DIY ideas out there regarding the cleaning of water softener systems, however, we truly feel that it is best to err on the side of caution and stick with methods that have been thoroughly safety tested, especially since our water supply will be in constant use by you and your family. 

Should I clean my water softener resin tank?

You absolutely should clean your water softener resin tank! We think that this is very important, and with the wealth of choice you have from our products above that can clean the resin tank and other parts of the water softener, we don’t see why you wouldn’t want to clean it!

There is certainly a common misconception that you “never” need to service them until the replacement interval of 15 to 20 years. However, in our opinion you should give them a good clean once in a while, especially as you will need to clean the whole system every few months anyway! You can guess when it is due to be cleaned when the tank regenerates more frequently than usual.

When should I clean my water softener?

The answer to this completely depends on your specific needs. We think, again, that it is better to be cautious. Many of the products we have listed above in our product review section state that they need to be used every few months. If you feel that your water supply needs it more often, then try it every other month.

Perhaps your water supply is relatively new and does not need cleaning that often, in which case once or twice a year may suit you. In fact, many of you may not have cleaned it for two or more years – that is fine!

Whatever suits you best is what you should do. Of course, if you are ever in doubt, perhaps because of metallic or sulfuric smells in your water, then there is no harm in giving it an earlier clean than planned! 

Final Verdict

As you can see, when it comes to choosing a water softener cleaner, the choice is immense. As we are sure you can see, there is a cleaner out there for all of your needs, whether that be to disperse rust, reduce iron, or just to generally clean it out.

Pick one of our products from the list above to be reassured that you have a great product, or use our Buyers’ Guide and Frequently Asked Questions section to inform your buying choice if you want to choose your own.

Whatever you choose, remember to check how compatible it is with your particular water softener system, and always follow the instructions set on the cleaning product to ensure the safety of you and your family. 

We hope this article and guide has proved helpful for you, thanks for reading!
