How To Remove Calcium From Water Naturally? | Quickly

Do you often notice white stains on your dishes and appliances after washing them? This is a sign of hard water, which is common in many areas. While hard water isn’t harmful, it can be frustrating. One of the main components of hard water is calcium, and removing it can seem daunting. However, there are natural methods to reduce the calcium content in your water significantly.

Calcium is a naturally occurring mineral that is found in many water sources. Hard water can cause build-up in pipes and appliances, making cleaning more difficult. Many people turn to expensive water-softening systems to combat this issue, but these can be costly and may use chemicals that are harmful to the environment.

Fortunately, there are natural and effective ways to remove calcium from water without using chemicals or expensive systems. In this article, we’ll explore some easy and affordable methods to soften your water and reduce its amount of calcium.

How Does Calcium Get Into Your Water?

Most of our drinking water originates from groundwater that seeps through layers of limestone rocks and earth, containing calcium compounds such as calcium carbonate. As the water comes into contact with these substances, the calcium is leached into the water.

This process helps to increase its alkalinity level, adding an extra protective layer against contaminants entering municipal aquifers. After this stage, most municipalities will treat the water with various pharmaceuticals and flocculants to remove any harmful particles or bacteria before they arrive at our homes.

Nevertheless, higher than usual levels may cause aesthetic issues such as staining of taps or poorer taste due to increased hardness levels. In extreme cases, further steps may be needed to reduce calcium in extremely hard water areas.

How to Remove Calcium From Water Naturally?

Removing calcium from your water source is known as softening of water and can be done through various methods. One of the most popular methods for softening water at home is a system specifically designed for that purpose. If you are still wondering how to remove calcium from water naturally, a few options are available.

Washing Soda

Washing soda is one natural means of softening water or removing calcium. Washing soda forms part of most soaps and detergents and can easily be found in your local store. It works by neutralizing pH levels thanks to its alkaline content, which breaks down the calcium ions in your water supply, reducing their content significantly.

You can add a small amount of washing soda to your standard drinking glass before consuming it, which will help reduce the hardness of your tap water over time. Another natural option for softening water naturally is boiling it for 10-15 minutes and then straining it into another container where the dissolved matter will settle at the bottom, leaving clean drinking/usage quality behind.

Lemon Juice

Lemon juice is a great natural cleaning solution for many tasks around the home. It can be found in the produce section of your grocery store and is easy to use. Using freshly squeezed lemons and putting the juice into a spray bottle allows you to apply it directly as needed. Taking caution not to let any get into your eyes, of course.

One of the best uses of lemon juice is cleaning metal surfaces, especially faucets. Not only does it clean and shine on these surfaces, but its acidic properties also help prevent rusting and discoloration caused by water damage or wear and tear over time.

An added bonus is that you can easily combine it with baking soda using a small sponge to create an effective cleaner. Lemon juice can also remove scuff marks on all surfaces, including tile floors, furniture, walls, and vehicle interiors, without creating any damage or abrasions.

White Vinegar

White vinegar is a versatile ingredient found in almost every household kitchen. This clear, mild vinegar is made from the fermentation of distilled grain alcohol, and when used as an ingredient in dressings or sauces, it adds a tangy flavor to meals.

Beyond its culinary uses, white vinegar has many distinct cleaning and deodorizing benefits. It can remove hard water stains on porcelain fixtures such as sinks and toilets. Applying a few paper towels soaked with vinegar to the stained area lets you watch calcium buildups quickly break down and wash away, leaving you with sparkling white surfaces.

Additionally, strong odors such as pet smells or smoke can easily be eliminated by spraying a solution of white vinegar throughout the room or furniture. For these reasons alone, it’s reason enough to keep this simple kitchen staple close at hand for cleaning projects big and small.


CLR is a powerful cleaning agent that removes calcium, lime, and rust deposits from plumbing fixtures. It is an especially effective product for toilet use, as the hard water in many areas can produce calcareous rings around the water line that are difficult to remove.

After the buildup has been treated and loosened with the CLR product, a simple rinse and scrubbing with a nylon brush will remove all limescale.

Most users find that applying CL in a thick coat on the surface and wrapping it around any outlet pipes or corners of toilets, bathtubs, or sink surfaces will do wonders after 10 minutes of treatment.

This allows time for Calcium Lime and Rust remover to penetrate through the deposit, breaking down molecules into smaller particles easier. With just one use, any noticeable deposits should be gone leaving your fixtures sparkling clean again.

Muriatic Acid

Muriatic acid is a strong hydrochloric-based acid that is highly effective in removing limescale and calcium deposits, making it an ideal descaler. Due to its potency, it can quickly dissolve the stubborn build-up that often causes plumbing issues.

It is perfect for effectively cleaning showers, toilets, and swimming pools. It should be handled with extreme caution because of its ability to cause permanent damage if exposed to the skin or eyes.

As the manufacturer recommends, safety measures should always be taken when using muriatic acid. This includes wearing protective clothing such as masks, goggles, gloves, and long-sleeved shirts and trousers, ensuring proper ventilation of the area being treated, and keeping it out of reach from children and pets.

In addition, all tools used for application must be selected cautiously so they do not react with the acid. Otherwise, there could be hazardous consequences. Due to its inherently dangerous characteristics, professional help is usually required when dealing with muriatic acid. With careful usage and following proper safety protocols, this cleaning agent can be used more safely while still reaping its full benefits.

Frequently Asked Questions [FAQs]

1. Can Calcium Be Boiled Out Of Water?

Boiling water can effectively remove calcium from water, but it depends on the concentration of calcium in the water. If the calcium levels are low, boiling will not effectively remove it from the water. Calcium has a high boiling point and will not evaporate with steam when boiling occurs. Other methods may need to be used to remove calcium from the water successfully.

2. Is White Vinegar Good For Removing Calcium From Water?

White vinegar can be an effective method for removing calcium from water due to its acidic properties. Vinegar is acidic and can break down calcium deposits on fixtures and surfaces in the home. When applied directly to hard water stains, it can quickly break down the buildup and easily wash away.

3. What Is The Best Treatment For Hard Water?

Hard water is a common problem in many areas, caused by excess minerals such as calcium and magnesium. The best treatment for hard water is to install a water softener, which will remove the calcium and magnesium from the water supply. Water softeners pass the hard water through a tank filled with small beads that attract and bind to the calcium and magnesium ions while allowing other benefits.

4. What Happens If Calcium Is High In Water?

If calcium levels in water are too high, it can cause several problems. Calcium buildup can form hard deposits on fixtures and appliances that use water, such as dishwashers and washing machines. It can also form scale on the inside of pipes, reducing flow and clogging them up. High levels of calcium can also create an unpleasant taste and odor in the water, making it unappealing to drink.

5. Is Hard Water Good For Your Hair?

Hard water is not typically ideal for hair because it contains high levels of calcium and magnesium, making it difficult to cleanse fully. These minerals can also create a buildup on the scalp and hair strands, leaving the hair feeling heavy and dull. This buildup may also cause dandruff, split ends, and other irritations. Additionally, hard water can interact with shampoo and conditioners to create a less-than-desirable lather.


Muriatic acid is an effective way to remove calcium from water, but it needs to be used with extreme caution and under the guidance of a professional. Other methods, such as boiling and white vinegar, can also be used to remove calcium from water, but they may not be as effective depending on the levels present. The best treatment for hard water is installing a water softener, effectively removing calcium and other minerals from the water supply.
