Cleaning Bluestone fireplace hearth

After taking off a child-safety protector around edges of Bluestone fireplace hearth, we now have two lines remaining from the tape residue that we can't get off. Any advice?

 

Dear Wendy:

Not much can be done, really. The acidity of the glue of the tape may have made a permanent etch-mark on your stone.

Try this: first you make sure to remove every residue of the glue by cleaning those lines with a clean white rag soaked with acetone (available at any paint store). Once we're sure that there's no glue anymore, if the discoloration persists but (temporarily) “disappears” if you wet it, the application of a good quality stone color enhancer like MB-6 will give you the same “wet look” (only darker, not any shiner) permanently. You do understand that this treatment will not actually repair the surface damage that you may have, but it will at least hide it from sight.
