How to Remove Hard-Water Stains From Natural Stone

Many homes use natural stone – such as granite and marble – as a material for countertops in the kitchen and in bathrooms. An unfortunate consequence of the porous nature of most natural stones is its susceptibility to hard-water stains. Cleaning natural stone tends to be a bit tricky, as acidic cleaners can deteriorate the stone's shiny finish, while others simply are not effective.

Things You'll Need

  • Sponge

  • Paper towels

  • 0000-grade steel wool

Step 1

Wipe the hard-water stains with a damp sponge to remove dirt or any other material that may scratch the surface of the natural stone.

Step 2

Dry the natural stone with paper towels.

Step 3

Buff the hard-water stains with 0000-grade steel wool in a clockwise motion. Buff just enough for the stain to disappear.

Step 4

Wipe the natural stone with a damp sponge, then dry with paper towels.
