Sharpie markers are easy to use, but they mark up your concrete sidewalk or driveway. The concrete has a porous surface, allowing the ink to seep into the tiny crevices. Washing the surface with water does not remove the ink since it requires a cleaner that pulls it to the surface. A product such as turpentine lifts the ink, allowing it to be scrubbed away from the concrete.
Sweep the Sharpie stain-marked area of the concrete with a broom to remove dirt and debris.
Drench the Sharpie ink stains with 1 to 2 cups of turpentine, depending on the size of the stains. Allow the turpentine one hour to sink into the concrete and dissolve the ink.
Pour one to two buckets of water over the stains to rinse the turpentine from the concrete.
Fill the bucket with warm water and 1 tsp. of liquid dish soap. Pour the soapy water over the remaining Sharpie stains. Scrub the stains with a stiff-bristle brush or shop broom. After scrubbing, rinse the area with a garden hose.
