A lot of users complait the fading of black granite counter tops. why does black granite fade?

The answer is, black granite should not fade.  Black granite imported from Asia is sometimes doctored with dyes and oils to darken the surface.  The fading is nothing more than the dyes and oils being removed.  Unfortunately, the only fix is to re-polish the top.  This can be costly.

Before purchasing a granite top perform the following test to find out if it has been doctored.  Take a clean white rag and apply a some acetone to the surface of the granite.  If any residue or black color is observed on the top, do not accept it, it has been dyed.
