My younger sisters efforts at scrubbing some dried food off the countertop yesterday were well aimed but not well executed. She used the scruffy end of a Brillo sponge (the green abrasive side) and now we have several small circles of shiny damage that can be seen when the light reflects off the countertop. How do I repair these "buffer-like" circles of damage? PS-The 'toothpaste remedy' didnt work.

Thanks
