NATURAL STONE - STAIN REMOVAL

What should you do if your natural stone stains?

1. Identify the stain before trying to remove it.
2. Act quickly! The longer it sits, the harder it is to get out.
3. Use a soft WHITE cloth or paper towel.
4. Blot don't rub.
5. Don't EVER use more chemicals than you need.

You can avoid stains on your Natural Stone by blotting up any spills immediately, thoroughly rinsing with a mild soap and water solution, and then drying the area.

In real life, this doesn't always happen. Maybe you didn't notice your best friend spilled her red wine on your beautiful stone bar until you got up the next morning. Or, your husband serves you breakfast in bed and the butter melts all over the countertop before you have a chance to get to it.

Whatever the reason, most surface stains can be removed by you with the help of an appropriate cleaning product or household chemical. Deeply embedded, stubborn, and/or metal stains usually require the help of a Stone Care Specialist.

Your first step in Natural Stone and Granite stain removal is to identify the stain. Not sure what caused the stain? Ask yourself a few questions:

  • Where is it?
  • What color is it?
  • What is the shape or pattern?
  • What goes on in the area around the stain?
