Why does black granite fade?

Q. Why does black granite fade?

A. 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. You may want to check out www.doctoredstone.org.

There is an excellent kit for testing to see if a stone has been 'doctored,' in the Stonecare PRO Signature line, called Stone Forensics Granite Test Kit. You can find it at www.stonecarecentral.com.

Keep in-mind that you can also use stone enhances to darken the counter top. Dyes are common in some stones at the quarries, solvents that are in most household cleaners will pull this dye out. Also keep in mind that some black granites have calcium binders in them and acidic cleaners will etch the stone. Use a natural Ph cleaner to help minimize the above issues.
