The panels have grease stains from food Description

I bought a dining room set that has blue slate panels in it. The panels have grease stains from food.  I was advised to remove the stains with soapy water containing
detergent with a degreaser. That made the spot worse. It is now dark in that area and (http://maplered.com) is worse than before. How can I get the slate cleaned
