Marble is highly susceptible to water rings and marks. When a glass is placed on a marble surface, condensation can drip down the outside of the glass and create a puddle of water. When the water evaporates, it leaves behind calcium and magnesium (hard water), which form a stain on the marble.

- Scrub the stain firmly until the water mark is removed.
- As you work be sure you keep the solution well mixed.
- Re-wet the cloth as often as needed.
- Allow the marble to air dry for a few hours or overnight. Don't rinse yet, let it dry.
