Granite countertops and flooring are a beautiful addition to any home, but granite is a porous surface that absorbs stains, making them difficult to remove. Salt deposit stains occur when hard water sits on a granite countertop for an extended period. The minerals in the hard water leave a white, flaky-looking spot on your granite. The longer a stain stays on the granite, the harder you will have to work to return it to its natural look. Taking proper care of your granite and cleaning it with products you have around the house will keep it looking as good as new.


Step 1

Dust the surface with a microfiber cloth.

Step 2

Using your razor, scrape the salt deposit. Place the razor flat on the surface of the granite. Use smooth strokes and slowly work the deposit buildup off the granite.

Step 3

Mix together a solution of one part rubbing alcohol, one part warm water and a few drops of Dawn detergent.

Step 4

Dip your sponge in the solution and rub it into the salt deposit. Rinse with warm water. Be sure to remove all of the solution, because leaving alcohol on the granite can dull it.

Step 5

Wipe dry with the microfiber cloth.


Reseal your granite countertop every two years. Do not use acidic products to clean, because they can etch the granite. Use hot pads on granite.


Do not allow alcohol or acid to sit on the granite surface.
