This can be almost impossible
to remove..First you must remove the silicon otherwise it will keep bleeding
through. I have had some success with methylene chloride in a poultice.
Sometime you can burn it out with a torch..but you have to be very very careful
not to get the granite too hot.

I have an issue that has come up recently involving a newly
installed a light tan colored granite counter top and an under
mount sink. It appears that when they installed the sink, they used some
sort of clear silicone that they claim to use all the time and it turned the
granite dark and began to come up through, to the surface of the granite.
Now, around the sink, about 2 inches out is stained really
dark. I have tried to use a product from Prosoco called Dicone NC9, which is a
silicone digestant, but with no success.
Does anyone know of anything else I could try?
Thanks
