Removing metal marks on tile & stone

In this renovation the owner wanted to keep his 1970's mosaic floor and remove all the walls. Anyone who ever used a power tool on tile and stone has left metal marks. There was a time when I believed that they were permanent because you can rub with any liquid until you're blue in the face and the mark won't budge.

A hermes silicone carbide 500 grit sanding disc makes short work of the mark. It only took light rubbing. 500 grit is the last of 6 grits you use to polish a bullnose on marble. The face of 500 grit sanding disc is a very fine abrasive material and has no effect on the tile glaze.
