11 Easy Ways to treat hard water

Water is considered to be “hard” when it has high levels of dissolved metals. It evaporates, leaving behind a mineral deposit.

These minerals can reduce water flow, clog appliances, and fade laundry. These are common problems, and how to treat hard water to resolve them, we’ll go over them all.

One common misconception about hard water is that it is harmful. Hard water can be beneficial for human health. It can help you get more minerals every day and protect you from disease.

How does it look? After washing your glasses, you will notice white chalky stains on the water fixtures.

We will help you eliminate hard water issues in your home by explaining everything we know, including the causes, signs, and treatment options.

Hard water symptoms

1. Soap Scum

The formation of soap scum in bathtubs, sinks, and showers can be caused by hard water. Soap curd can stick to surfaces when hardness minerals in the water combine with soap.

The scum remains behind when water goes to the drain. It leaves a thick, unpleasant-looking film.

2. Scaled surfaces

A white chalky mineral buildup can often be seen where water evaporates. It leaves behind dissolved magnesium and calcium ions and is hard to get rid of.

3. Dingy Laundry

Hard water may cause your clothes to look dull after just a few washes.

It is especially evident when washing whites. This soap scum can also build up in tubs and sinks, and it can collect on clothes after wash.

4. Scale water fixtures

Scale buildup is a cause of hard water problems and eyesores around your water fixture. Hardness minerals form when hard water flows through the showerhead or faucet.

These deposits can build up over time and cause water flow problems.

5. Scale Deposits in Water Pipes

Scale buildup can also clog water pipes, just like it does on fixtures. The mineral deposit can build up in water pipes, reducing water pressure even though you don’t see them.

It can cause pipe replacements or other problems in your home, especially in extreme cases.

6. Failure of Water-Using Appliances

Scale buildup can affect water-using appliances, particularly those that heat or use heated water like a water heater, dishwasher, and washing machine.

The buildup can ruin efficiency and, over time, cause appliance failure. It can cost you money in repair costs, replacements, or increased energy consumption.

7. Hard water causing hair and skin problems

To get a lather with hard water, you will need more shampoo and detergent. However, it won’t rinse off skin or hair.

The remaining residue can cause dry, itchy skin and unmanageable hair. It can be a hard water problem for colored hair or those with treated hair.

8. Determine how severe your hard water is.

Specifically, the milligrams/liter (mg/L) measurement indicates your water hardness ion. This measurement may be referred to as parts-per-million (ppm) in some cases.

These are the water hardness ranges, according to the Water Quality Association.

Soft: mg/L <17

Slightly Hard: mg/L 17.1 – 60

Moderately Hard: mg/L 60 – 120

Hard: mg/L 120 – 180

Very Hard: mg/L >180

How to treat hard water with 11 ways?

Softened water is essentially about removing hard water minerals that cause hardness as calcium or magnesium.

There are 11 effective methods to treat hard water. The method you choose will depend on whether all of the water needs are met or just a few.

Chemical-hard water treatment options

1. Use washing soda for laundry

Washing soda is one of many best ways to treat hard water. It is a chemical of carbonic acid salt (sodium carbonate ion). It can soften both permanent and temporary hard water.

Washing soda removes calcium and magnesium from water, and as a result, you get soft water quality. It makes it easier to use soaps.

2. Treat Temporary Hardness with Boiling

It is an easy way to soften hard water at home. Temporary hard water is water that contains a lot of calcium carbonate ions. Softer drinking water is possible because boiling reduces water’s calcium content.

Boiling is an inexpensive and quick way to make hard water drinkable. It can only fix temporary hardness and not permanent. It contains dissolved calcium sulfate, which boiling won’t remove.

3. Use Distilled White Vinegar for Hard Water Stains

Calcium is naturally alkaline, meaning that its pH level is higher than 7, whereas the standard pH of bottled water is around 7.

It is reactive with acids such as vinegar because it makes up the majority of hard water.

For small fixtures with calcium buildup, you can place them in a bowl of warm, all-natural vinegar. It will dissolve the calcium mineral deposit within about an hour.

Distilled vinegar is another water treatment option for spot and white film problems. It kills bacteria, mold, and germs, as well as cleans dishware with regular washing cycles.

A buildup of soap scum may occur from water. It is possible to rinse the scum with just one part apple cider vinegar and three parts filtered water.

4. Use a hard water cleaning aid to remove soap scum

The scum forms when the soap chemicals and dissolved minerals in hard water react to each other. Lime soap is the white buildup on water fixtures and accumulates in tubs, sink drains, and tiles.

The positively charged calcium ions in the water cause soap scum to form. 

These atoms stop soap molecules from dissolving. Instead, undissolved molecules attach to surfaces and accumulate.

Use a water cleaning solution to fix these side effects. These products contain a solution to counter the negative atoms found in hard water. 

These products make it easier for soap to be rinsed away and prevent them from forming scum.

Mechanical-hard water treatment system options

5. Use RO system to treat hard water

RO may seem a bit confusing, but we have the answer. Reverse osmosis systems force water through many fine filters.

Many people use RO to get softened water benefits. It will eliminate any solid contaminants, such as organic materials and chemicals.

If you are looking for, contaminant-free soft water with no added salt, then reverse osmosis is a great choice to treat hard water at home for drinking.

It can provide great tasty quality water, like packing bottled water at an affordable price.

Although, RO systems can only supply water to one point of your home unless you have multiple devices.

Reverse osmosis systems can increase water consumption, and regular cleaning is necessary to maintain water safety. A dirty filter is better than none!

Keep This in Mind

All nutrients will be removed by the water filter. It can lead to a deficiency of essential minerals, which is unhealthy in the long term.

6. Ion-Exchange water softener

The most efficient method to get soft water is an ion-exchange system.  The hard water minerals that are not purified are exchanged with sodium ions during the ion exchange process.

Only sodium ions are left behind, but no magnesium or calcium is in this ion exchange process. These systems usually come with two tanks.

  • Resin tank.
  • Brine tank. 

Dual tanks are also available for systems. It will help reduce the downtime during system regeneration by having an extra resin tank.

You can add the following types of water softener salt (Sodium chloride):

Rock salt: This is a cheaper option. However, it has more insoluble substances that can build up in the tank and valves. They also require frequent cleaning.

Evaporated salt: Evaporated salt is purified and finer than regular salt. Table salt is an example.

Solar salt: The sun warms the brine pond, and then solar salt (sea salt) is extracted. Sodium chloride crystals are left behind when the water evaporates.

It is also a good source to make alkaline water at your home.

Ion exchange softener provides great water while preventing developing scale deposits and improving your appliance like washing machine, water heater, and dishwasher.  

7. Magnetic or Electronic Water Softener

A magnetic or electronic softener or descaler is one of the latest water softening systems to fix hard water in-house

These devices can be plugged into an outlet or clipped to an indoor pipe that allows water to enter the house. 

They create magnetic fields which alter the electromagnetic properties of the dissolved minerals. It makes the carbonates repel each other and reduces mineral buildup.

However, these devices are not supposed to remove hardness ions like the ion exchange system.

They alter the electromagnetic properties and prevent magnesium and calcium carbonate ion buildup.

8. Showerhead water filter softener

If you feel the effects of hard minerals, then showerhead filters can be helpful to treat hard water for hair and skin.

These filters can be easily installed in your shower to filter mineral ions and contaminants as the water leaves the tap.

A showerhead filter can reduce limescale and remove mineral content that can block water pipes. 

The investment is worthy to soften hard water for bathing, hair, and skin without soap scum created.

9Demand Initiated Regeneration System

Demand Initiated System can monitor regular water consumption and only regenerate when it is needed. The systems can be set up to run on a schedule for a specific time.

Some of these systems can run out of water at times of high demand. They are also not eco-friendly because of treated ions and release a very salty solution into the sewer system.

10. Nucleation Assisted Crystallization (NAC) or Template Assisted Crystallization (TAC) system

These systems can make soft water with no salt and a healthier alternative to ion exchange. Are they better?

Take Note

The salt free water conditioner doesn’t work as a softener. These softeners are often called water conditioners or water dealers. 

It is difficult to measure water softness if minerals remain in the water.

TAC and NAC systems don’t remove mineral content. They alter the form of minerals so that they don’t stick to any surface.

The water flows through a TAC medium where the mineral hardness ion of the water converts into a crystal. That is indestructible to any surface.

You’ll get the same results when you test the hardness after and before water treatment.

TAC systems, which don’t require water or energy, are an excellent option if you want to be greener.

11. Chelation water softener

You can also use a chelation system as a salt-free water conditioner, similar to TAC. These systems allow the mineral ions to adhere to a chelating agent like nitriloacetic.

It results in minerals being suspended in the water.

This system will not reduce the hardness of minerals, but it will prevent them from being scaled. It reduces the buildup of limescale minerals.

That makes it a great option to treat hard water for plants because it keeps the water’s healthy minerals intact while preventing scale.

It would be much easier to get rid of limescale and buildup if it were to occur since the ions don’t stick to any surface.

What is the best treatment method to treat hard water?

There are many ways to fix hard water issues in your home. Depending on how severe your hard water problem is, you can choose the best water treatment.

You may not notice any signs if you have hard water. In this case, vinegar and hard water cleaning products might be a good option.

You should invest in a descaler if your water is moderately or more hard. This will ensure that your plumbing system doesn’t get damaged.

Our low-maintenance Salt Free Water conditioner is recommended to avoid scale buildup and preserve the health benefits of your soft water. 


If you’re new to water softening, it can be difficult to choose the right one.

While considering how to treat hard water, you want your drinking water to be clean, fresh, and tasty. An ion exchange system is the best option for you.

Salt-free systems like TAC can be a great solution if you want to minimize the harmful effects of hard water and still get healthy minerals.

Installing a reverse osmosis filter is a better option if you have moderately hard water.
