From what I have read.. a doctored slab will reveal itself  after being exposed to spilled soda, juice,lemons . Wouldn’t something like M.E.K or Phosphoric acid work if you didn’t have access to a test kit ?

Fred. Is there a DIY way for this testing? Is the kit small? I have shipping issues being in Australia.

Tony,

 

The light marks maybe from a calcium binder that is in the granite and that area actually etched lightly. You may need to hone the granite ( Use Granite Diamonds) I would try starting around a 400 to see if the ring hones out . then hone the area up to 3000 be sure to feather each grit. Then I would polish using a Dark granite polishing powder, crystallizer and steel wool . This should correct you problem. If the etch is not too deep  try jus t polishing it out first. Let me know if you have any questions, sorry for the delay in my response I had class all this week

I have a client with a jet black Granite countertop.  It has light ring marks from the bottom of glasses and an area that looks like a small spill.  The marks are a very light whitish color that does not show up in a photo.  There is no topical sealer or waxes on the Granite.  Any ideas of what it is and how to correct it?

 

Thanks,

 

Tony
