cleaning orange juice stains on marble tiles

Dear Marie:

The orange juice “stains” that you have on your stone are marks of corrosions (etchings) made by the citric acid contained in oranges that became in contact with the surface of the stone. There's no product on the marketplace – sealer or what-have-you – that could prevent such surface-damages from happening. You will need the services of a bona fide stone restoration contractor, who will have to hone and re-finish your stone. You could also take a look at MB-11. If the etching is not to severe, you could be able to fix the damage yourself.

May I ask you now to please read and e-sign our Statement of Purpose at: http://www.marblecleaning.org/purpose.htm? J

Ciao and good luck,
