You can remove calcium deposits by using cleaning products available at most grocery or other retail stores. These products may have sequestrants, substances that deactivate minerals, in them. If you don't want to use this type of cleaning product, you can also use bleach to clean off stains. Distilled white vinegar can remove calcium as well, and it's especially useful for cleaning coffee pots and pipes.

To remove calcium deposits from a faucet using vinegar, soak a washrag in vinegar and tie it around the faucet. This can also work if the vinegar is placed in a plastic bag and the bag is tied around the faucet. After a few hours, the bag or rag can be removed. If there are any deposits remaining, they can be removed with a toothbrush. Pouring vinegar down a drain, following it with baking soda, and then rinsing thoroughly with water can also remove calcium in the pipes.

Lemon juice can also be used in place of vinegar. You may also use bleach to remove some stains, but if you do, it's important to rinse it off quickly so that it does not harm surfaces. For those stains that will not respond to vinegar, it's often best to use a cleaner from the store. These cleaners often have some sort of acid in them that allow them to eat through the calcium deposits. Phosphoric acid, for example, is used in some products that remove hard water stains.

Remember that, even after you've removed the mineral deposits, they are likely to return. Calcium deposits are caused by high amounts of minerals in tap water, which remain on surfaces after the water evaporates. These stains should be removed quickly because the longer the minerals sit, the more they can penetrate into the surface, and the harder they can be to remove. Some people may find that a water softener can help to prevent the initial buildup of calcium stains.

@anamur-- Unfortunately, there aren't many natural products that remove calcium deposits. I had hard water stains and calcium deposits in my shower. Vinegar didn't do a thing. I could only remove them with the strongest shower cleaner from the store, followed by water with bleach.

@anamur-- Have you tried vinegar? White distilled vinegar always removes calcium deposits from glass for me. I soak a washcloth with vinegar and let the calcium deposits absorb it over several hours. Then, I brush them off.

Vinegar doesn't smell too great either, but at least it's natural and safe. You could also try lemon juice but I personally have never tried it, so I can't comment on that.

Does anyone else have any ideas to add?

Is there a product that removes calcium lime deposits without harsh fumes?

I have asthma and I can't use any cleaners with chemicals in them. The fumes trigger an asthma attack. I need something that will remove the calcium without killing my lungs.
