Designing Kitchens and Bathrooms - Removing Epoxy Glue from Granite Sink

I had new granite countertops and an undermount black granite sink installed in my kitchen yesterday. Just before the contractor left, he wiped down the sink with a rag that was filled with epoxy glue (which he used to glue down the countertops). It ruined the inside of the sink -- it looks like someone spilled gray paint in the sink and swirled it around. Does anyone know of a way to remove this epoxy residue and restore my black sink back to new??? Please advise!

I have called the company and complained, but they can't come out and inspect the work until next week. Right now it looks like they'll have to give me a whole new sink, which means they'll have to rip out all the countertop and start anew. I would rather not go this route.

Thanks for any advice anyone can give.

My first thought is to try goof off..not the latex but the oil based product.

Granite is pretty tough stuff, its survived in the ground for several million years. Go to www.marblecleaning.org and ask one of the pro stone refinishers what to use. Be sure to tell them the name of your granite as what works well on one type of stone wont work on another type due to the geological/chemical makeup.

Epoxy is sometimes tricky to work with, and will delaminate fairly easily if the surface had any kind of residue on it. It couldn't hurt to fill the sink with water and let it sit for a few hours. Then you may be able to peel the epoxy from the sink in sheets (like sunburned skin). It's a long shot, but it couldn't hurt anything to try.
