Harmful Effects of Calcium Buildup in Water

Calcium buildup in water is a common problem that can bring about adverse effects. This buildup is usually visible in the form of white or yellowish deposits on faucets, showerheads, and other household appliances that come into contact with water.

The buildup can also clog pipes and reduce water flow, leading to costly repairs. While it may seem innocuous, calcium buildup can also negatively impact our health. Drinking water with high calcium levels can lead to the development of kidney stones, as excess calcium can’t be absorbed by the body and instead accumulates in the kidneys. Furthermore, skin conditions such as eczema and dryness may occur due to the presence of high minerals. It’s important to stay vigilant and take measures to reduce calcium buildup in our water to avoid these harmful effects.

How to Remove Calcium from Faucet

One simple way to remove calcium build-up is to soak a cloth in white vinegar and wrap it around the affected area. Leave it on for a few hours, then scrub the area with a toothbrush

Step-by-Step Guide for Removing Calcium Buildup

  • Prepare the necessary materials: white vinegar, a plastic bag, a rubber band or zip tie, a soft cloth or sponge, and an old toothbrush are all required.
  • Fill a plastic bag with enough white vinegar to completely submerge the problematic region of the faucet. If you prefer a more diluted solution, combine equal parts vinegar and water.
  • Soak the problematic area: Place the vinegar bag over the faucet, making sure that the accumulation is completely submerged in the solution. Use a rubber band or zip tie to keep the bag in place. Allow it to soak for at least 1-2 hours, or overnight if the buildup is really persistent.
  • Remove the bag and scrub: Carefully remove and discard the plastic bag from the faucet. Dip a delicate cloth or sponge into the vinegar solution. Wipe away the loosened calcium deposits with the moistened towel. Scrub the area gently with an old toothbrush for more tenacious accumulation.
  • Rinse and dry: After removing the calcium deposits, thoroughly rinse the faucet with water to eliminate any leftover vinegar residue. Wipe the faucet dry with a clean, dry cloth to remove any watermarks.
  • Buff with a paste (optional): If there are still some stubborn spots or if you want to restore the faucet’s shine, you can make a paste using baking soda and water. Apply the paste to the affected areas, scrub gently, and rinse with water.

How do you remove hardened calcium?

  1. One option is to use a vinegar and water solution, which can help dissolve the hardened calcium and make it easier to wipe or scrub away.
  2. Another approach is to use a commercial lime and calcium remover, which can be found at most hardware or home improvement stores.

How do you remove hard water crust from the faucet?

 One easy and effective way to remove hard water deposits from your faucet is by using white vinegar and a soft cloth.

  1. Gather the necessary materials: You will need white vinegar, a soft cloth or sponge, an old toothbrush, a plastic bag, a rubber band or zip tie, and mild dish soap (optional).
  2. Create a vinegar solution: Fill a plastic bag with white vinegar, enough to fully submerge the affected area of the faucet. If the buildup is extensive, you may need to detach any removable parts of the faucet and soak them separately.
  3. Soak the faucet: Place the plastic bag filled with vinegar over the faucet, ensuring that the hard water crust is fully immersed in the solution. Use a rubber band or zip tie to secure the bag in place. Leave it to soak for at least 1-2 hours or overnight for stubborn crust.
  4. Remove the bag and wipe the faucet: Carefully remove the plastic bag and dispose of it. Take a soft cloth or sponge and dampen it with vinegar. Wipe the faucet to remove any loosened crust. If necessary, you can also add a small amount of mild dish soap to the cloth or sponge to help remove any remaining residue.
  5. Scrub stubborn areas: For stubborn hard water crust, use an old toothbrush dipped in vinegar to gently scrub the affected areas. Apply light pressure and scrub in circular motions to avoid scratching the faucet’s surface. Rinse the toothbrush and faucet periodically to remove the loosened crust.
  6. Rinse and dry: Once you have removed the hard water crust, thoroughly rinse the faucet with water to remove any vinegar or soap residue. Use a clean, dry cloth to wipe the faucet dry and remove any water spots.

If the hard water crust persists or if you prefer a stronger solution, you can also use a commercial lime and mineral deposit remover following the manufacturer’s instructions. Be sure to read and follow any specific instructions or warnings provided by the faucet manufacturer or the cleaning product you choose to use.

How To Prevent Calcium Buildup On Faucets

The best way to do this is by keeping your faucets dry after each use to prevent water from sitting and allowing minerals to accumulate. Or you can follow these steps:

  1. Regularly clean down faucets: After each usage, wipe off the faucets with a soft cloth or sponge to eliminate any water residue. This aids in the prevention of mineral deposits forming and hardening over time.
  2. Install a water softener: If your neighborhood has hard water, consider installing a water softener system. Water softeners remove minerals from the water, such as calcium and magnesium, lowering the risk of buildup on faucets and other fixtures.
  3. Install a faucet aerator: A faucet aerator combines air and water to reduce the force of the water flow. This can help to reduce mineral buildup by preventing the splashing and spreading of minerals on the faucet. Furthermore, some faucet aerators feature built-in filters that can capture silt and minerals, reducing buildup even further.
  4. Clean with vinegar: Use white vinegar to clean your faucets on a regular basis. Vinegar is a powerful natural cleanser capable of dissolving mineral deposits. Apply vinegar to the faucets, dilute it with water, and scrub gently with a soft cloth or sponge. After that, thoroughly rinse with water.
  5. Use a commercial lime and mineral deposit remover: Use a commercial lime and mineral deposit remover made specifically for faucets and fixtures. For safe and effective use, follow the manufacturer’s directions.
  6. Avoid abrasive cleaners: Avoid using abrasive cleaners or scouring pads on your faucets, as they can scratch the surface and make it more prone to buildup. Instead, opt for mild, non-abrasive cleaners or natural cleaning solutions like vinegar.
  7. Regularly clean faucet aerators: Remove and clean faucet aerators every few months to prevent mineral buildup. Soak the aerator in vinegar or a lime and mineral deposit remover solution to dissolve any accumulated deposits, then rinse it thoroughly before reattaching.
