We shall go ahead and review five of the best water softener cleaners currently available in the market to give you a taste of the features and later break down the criteria we used to come up with the list. But before that let’s look at when should you clean your water softener so you don’t use the cleaner in vain and waste money.

Best Water Softener Cleaner: Our Top Choice

When Should I Clean My Water Softener?

In simple words, be aware if your water softener is regenerating more than usual. Minerals like magnesium and calcium passes through the resin beads of resin tank. In this process those minerals stick to the beads and reduce the hardness of the water. This happens automatically and the resin beads flush itself to maintain cleanliness.

So, there is a misconception that water softener do not need cleaning as it cleans itself. But, eventually these resin beads get overwhelmed by minerals and starts to regenerate more often than normal and it need outside help. That’s the perfect time to clean water softener to prevent any damage from happening to the resin tank.

In the brine tank that contain salt pellets look for any mold, salt bridges or sludge. If you see any of it forming, it’s time to clean.

If you want to avoid the problem of brine tank completely, you may look for Salt Free Water Softeners.

How often should you clean a water softener resin tank?

Resin tanks need more attention compared to brine tanks. In my experience, resin tanks should be cleaned once every three or four months to prevent damaged resin beads. It should be enough if you clean the brine tank once every year. 

Cleaning frequency mainly depends on the hardness of the water of your locality. More hardness means it needs cleaning more often.

Hard Water vs Soft Water

Water can be classified as hard if it has at least 60mg of dissolved calcium and magnesium. Many water sources provide some level of hard water with various concentrations of dissolved minerals like calcium, magnesium, and iron.

These minerals contribute to some unfavorable qualities in the water that make it essential to remove them. The water tends to leave cloudy markings on sinks, bathtubs, showers, and your silverware.

It becomes hard to lather soap, and you suffer dryness and itchiness after bathing using this water. It also leaves mineral deposits as it runs through the system, which can block your pipes, showerheads, and valves or plug aerators.

These scenarios build up pressure on your plumbing system and may lead to severe damages. Your water-dependent appliances like ice machines, dishwashers, and coffee makers will also suffer a shortened lifespan.

The work of water softeners is to remove these minerals from the water, making the water ‘soft.’ They save you hours of cleaning up soapy water residues and scaly faucet heads and the cost of replacing prematurely ruined water heaters. They are a water filtration system for the entire house.

How Does a Water Softener Work?

Before we can fully appreciate the important role of water softener cleaners, we need to understand the workings of the water softener to be clear on why we need them.

The water softener has a mineral tank with specially formulated resin beads through which water is passed. The resin possesses a negative charge which attracts the positively charged minerals in the water. These minerals then stick to the water softener resin as the now softened water flows onto your water outlets all over the house.

The resins exchange their sodium ions for hardness ions. Over time, their capacity to soften water depletes, and they can no longer attract the mineral ions. At this point, the softener tank needs to be regenerated or flushed clean.

There is a separate brine tank for this purpose that is connected to it. Salty water from the brine tank flows into the softener tank for the rinsing cycle to commence. It washes the mineral deposits off the resin beads, and the regenerated water is flushed out along with the mineral deposits.

The brine tank contains salt pellets or potassium chloride, which slowly dissolve during the regeneration process and should therefore be added periodically depending on how much water is utilized. These are what it uses to wash mineral deposits off the resin beads.

The resin tank has a control valve at the point where the softened water leaves the tank. It measures the amount of water that has passed through your water softener tank for tracking purposes. It is used to program the auto regeneration interval.

The Role of the Water Softener Cleaner

Once the resin has attracted calcium, magnesium, iron, and all those trace minerals that make the water hard, its capacity to keep attracting them dwindles. Water softener cleaners have been fashioned specifically to remove mineral build-up. They replace the minerals with sodium ions.

If you discover that the resin beads have too much of one element, this is an indicator that the element is dominant in your water source. You may opt to choose a cleaner that targets the particular element.

The water softener is usually poured into the brine tank, but it can be fed directly to the salt tank when there is no brine tank. This should be done when the salt content is low so that it has maximum impact.

How to Determine Your Best Water Softener Cleaner?

As much as they work similarly, certain considerations will make others more suited for your particular circumstance than others. The right cleaner depends on what you intend to clean, so you should start by testing the water.

Below are some of the qualities that set them apart from each other that will influence your decision.

💧Drip Feeder Water Softeners

These employ some kind of continuous feeding system where a reservoir is attached to the inside of your brine tank and keeps dripping into it. This means your resin bed will be cleaned every time there is a regeneration. It will be part of the salty water coming from the brine tank.

The consistent cleaning keeps your resin capacity high, and they can filter out those minerals more thoroughly. They use weak acids that dissolve iron by lowering their pH. They are not the best for removing iron fouling but are quite adept at preventing it.

💧Iron and Manganese

These are difficult metals to get rid of and require dedicated cleaners to take care of them; otherwise, they may end up getting deposited in your water softener tank, leading to all kinds of problems. These cleaners are usually labeled and should be easy to identify.

💧Powder vs Liquid Water Softener Cleaner

The form in which the cleaner comes determines how it will be applied to the water softener. Powder cleaners should be given time to form brine before the cleaning process as it is not effective while in its dry state.

💧Value for Money

Take into account the complete package that you are getting with your purchase. It is not sufficient to just look at the price. If it has a drip feeder option, are you purchasing the feeder separately? Also, look at the quantity you are getting in comparison to the price.


Beyond metals, there are molds, bacteria, and algae, which can also attach to your water softener. The water softener cleaner should be able to take care of these impurities as well. They also affect the quality of water and have a direct impact on your health.


Most water softener cleaners are universal, but it should not be taken for granted that they will work with your particular type of water softener. Some are only compatible with their particular brand, and you should confirm this before you make your investment.

💧Odor and Taste

The water softener cleaner you use should not leave an aftertaste or scent. This water will be all over your house, and this can be irritating and nauseating.

💧Advanced Cleaning Technology

The water softener cleaner with the ability to get rid of the most impurities is the better option. Its cleaning ability should cut across as many metals, microorganisms, and dirt as possible. This ensures you don’t have to invest in multiple cleaners for every vice.

💧Ease of Pouring

Some cleaner containers are not ergonomic at all. They are either too big or lacking convenient handles with which they can be poured. This action requires a bit of precision, and there can be losses if you are unable to aim correctly.

Water softener cleaning is a practice that should be engrained in your household routine as it has far-reaching implications on the quality of water that you will use in your house. The effort involved is negligible if you weigh it against the benefits.

This level of efficiency increases the lifetime of your water softening system, guaranteeing you receive full value for your investment.
Some manufacturers require you to use water softener cleaners to maintain the warranty of your water softener.

3. Can I put vinegar in my water softener?

Vinegar has been used as a water softening agent for a long time. You can use it to clean the water tank as it will not harm your water supply. It leaves an aftertaste for a while, though, but that depends on the kind of vinegar you are using.

4. What is water softener resin cleaner made of?

The most common elements are butanone and acetone, which are solvents that can dissolve other materials, allowing them to be great cleaning agents. They also have some form of acid in their DNA, like acetic acid, allowing them to lower pH and dissolve metals.

5. How do you keep your water softener in top-notch condition?

Modern Water Softeners are generally self-maintaining. Here are a few tips for extra care:
☑️Clean the venturi valve– This is responsible for the suction motion that moves brine from the brine tank into the resin tank during regeneration. Occasionally dirt gets stuck in it, and this could hamper the operation of the whole system.
☑️Use a Resin Bed Cleaner– As much as the system is self-regenerating, every once in a while, the water softener will become polluted by metals that the normal salt can’t get rid of. A water softener cleaner provides that extra thoroughness.
☑️Be Extra Careful with Your Choice of Salt– Look for the highest purity level in your salt because they are least likely to leave residue in your storage tank. A muddy tank will have less softening efficiency and is more likely to leave impurities in your water. Evaporated salt is the purest, followed by solar salt and then rock salt.
☑️Watch Out for Salt Bridges– This occurs when a large crust forms in the brine trunk, preventing the salt from dissolving in the water to make brine. The resin beads can’t function without the brine as they will lack the capacity to attract ions.

6. How often should you clean your water softener?

The accurate answer is every time, it needs to be cleaned. The variables include the volume of water being used and the water level, and the type of hardness. Some metals like iron are tough to remove with just salt and may force you to clean your water softener more than others.

The higher the level of hardness, the more you will be required to clean it. If you use more water, the cleaning cycle automatically becomes shorter.
