Water stains can be removed from a marble surface using a home remedy of baking soda and water. If no baking soda is available, it is also possible to remove water stains from a marble surface using dish soap, white vinegar and water.
To remove water stains from a marble surface using baking soda and water, first combine both ingredients to create a thick paste. Use a soft cloth to rub the paste onto the affected area, cover with plastic and leave to sit for up to 24 hours. After the allotted time, remove the plastic wrap and rinse the paste off. Finish by drying the area with a dry soft cloth.
It is also possible to clean water stains on a marble surface using dish soap, white vinegar and water. Begin by drizzling a couple of drops of dish soap onto a soft cloth, and scrub the affected area vigorously. Rinse the affected area and examine to see if any water stains remain. If stains are still visible, dip a soft cloth in white vinegar and scrub gently to remove the remaining marks. Finish by rinsing the surface and drying with a clean and dry soft cloth to prevent streaks from forming.
