How do I clean oil stains in yellow marble?
Marble can be easily stains because of its porous nature.
Try covering the area with corn starch for about 24 hours. It will absorb any excess oil. Then, wash the area with more hot water and detergent. If you still see the stain, dampen a paper towel with acetone. Leave the dampened paper towel on the stain for about an hour, and rinse with water. Repeat this process untill the stain is completely removed.
