George Foreman Grill Left Marks on My Laminate Table?

I have an old (first generation) George Foreman grill that I found in a cupboard when cleaning. I put it on a laminate table top and forgot about it. When I moved it there were black round spots on the table. They will not come off even with the Magic Eraser. Has anyone found a method that works to remove these marks without causing damage to the tabletop?
