A person can remove calcium deposits by using cleaning products purchased from the store. These products may have sequestrants, substances that deactivate minerals, in them. If a person does not want to use such a cleaning product, he or she can use bleach to clean off stains. Distilled white vinegar may also be used to remove calcium deposits. Vinegar can be used in a variety of areas including cleaning coffee pots and pipes.

To remove calcium deposits from a faucet using vinegar, a person can soak a washrag in vinegar and tie it around the faucet. This can also work if 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 deposits.

In order to remove calcium deposits from a tea kettle, vinegar and water can be placed into the kettle and allowed to sit overnight. A person can also pour pure vinegar in the kettle, boil it for a few minutes, and then rinse the kettle thoroughly once it has cooled. Vinegar can also be used to remove calcium deposits from coffee makers. To do this, a person can pour vinegar into the water reservoir, allow the coffee maker to brew, and then repeat the cycle with plain water at least twice to rinse.

Lemon juice can also be used in place of vinegar to remove calcium deposits. A person may also use bleach to remove some stains, but it is often recommended that the bleach be removed quickly so that it does not harm surfaces. For those stains that will not respond to vinegar, a person may have to purchase a cleaner from the store. These cleaners often have some sort of acid in them that allow them to remove calcium deposits. Phosphoric acid, for example, is used in some products that remove hard water stains.

When attempting to remove calcium deposits, a person should always remember that deposits can return. Calcium deposits are caused by high amounts of minerals in present in water. When this water evaporates, calcium and other minerals are left behind and can build up. These stains should be removed quickly because the longer the stain sits, the more it can penetrate into the surface, and the harder it can be to remove. Some people may find that a water softener can help to prevent the initial buildup of calcium stains.
