How Do You Remove Water Marks From Marble?
Remove water marks from marble by covering them with a paste made from baking soda and water before scrubbing them with steel wool, if needed. This process requires baking soda, water and steel wool. Completely removing stubborn water marks is a two-day process.
Wash and dry the marble
Wash the marble with a damp cloth, and dry the area thoroughly. Inspect the area for water marks.
Apply the baking soda paste
Mix baking soda and water together to form a thick paste. Apply the paste to the water marks with a soft cloth. Cover the paste with plastic wrap, and allow it to sit for 24 hours.
Rinse off the baking soda
Remove the plastic wrap, and rinse off the baking soda. Dry the area with a soft cloth, and inspect the area for any remaining marks. Take note of areas that require further treatment.
Scrub with steel wool
Using steel wool, scrub the remaining water marks in a circular motion. Rinse and dry the area frequently to examine the progress being made. Once the marks are gone, rinse the area with water, and use a soft cloth to dry it. Maintain the surface by cleaning up any spills as soon as they occur.
