Hard water buildup often will leave hard-to-clean calcium deposits in your sinks and showers. Although you can try to soften the water with a commercial-grade filter, sometimes the best you can do is apply a home remedy to clean the calcium deposits. The materials to clean calcium deposits are inexpensive and common to most kitchens.
Vinegar is a natural way to rid your home of unwanted calcium deposits. Pour 2 cups of white vinegar into a spray bottle with 1 cup of hot water. Spray the mixture onto the calcium deposit, and allow it to soak for several minutes. Then use a rag to rub the area clean of the calcium deposit. Spray this solution whenever you need to clean calcium deposits; it is safe to use around children and pets.
Tang is a powdered drink beverage mix available in most supermarkets. Tang contains a high amount of ascorbic acid, which will eat away at the calcium deposits. Spread the powdered Tang on the calcium deposits and allow it to sit for several hours. Then use a cloth dipped in hot water to scrub your calcium deposits, and they should come clean.
Tartar & Peroxide
Make a paste using cream of tartar and hydrogen peroxide and apply it to the calcium deposits--the paste should be three parts cream of tartar to one part peroxide. Allow this to sit for 10 minutes. Once the paste has had a chance to work, you will need to take a cloth soaked in warm water and rinse away the calcium deposits. You may need to do this several times to remove all of the deposits.
You may need to apply these home remedies several times in order to clean all calcium deposits. Preventive maintenance will help keep the deposits to a minimum. When cleaning these deposits, make sure to wear gloves and keep the area well-ventilated.
