Question
We have water spots that won't come off our black marble countertop. The sealer that was recommended did not do the job.
My wife loves everything black...and no she's not a witch.I made the mistake of concurring on black marble countertops.
Answer
Richard,
Mix up a paste of baking soda and water to the consistency of tooth paste. With a rag rub a small amount of the mixture onto the area of the water spot in a circular motion.
For what it's worth this also works well on stains on a corian top stove.
Good Luck.
