Stain From Silicone Sealer

Dear M, We our contractor installed a sink in our Pearl Black granite countertop and used a clear silicone seal for around the edge of of the top mounted sink. The granite is honed and now we have a dark, shiny ring around the sink and some spots, as well. We tried Acetone, but it didn't really have much effect. Any suggestions? Regards, Dave
 

I doubt that they used 100% silicone seal: it does not do that. Maybe they used Plumber's Putty or something similar.

At any rate, the stain is there and we have to try to remove it.

First you must eliminate the cause of the stain: that sink must be disassembled and all the stuff that stained the stone must be scraped off from the bottom of the slab. Once this is done, you should be able to remove the stain using a potent paint stripper based on Methylene Chloride. (Read and follow all precautionary directions printed on the container of the product.)  Most likely you will have to go through several attempts.

But now that you know what product to use, the question is: How?

When it comes to stain removal, either you buy one of those expensive “Professional kits” (that true professionals seldom use!) at a stone retailer near you, or you can spend less money and get our comprehensive guidelines on how to remove stains by using inexpensive and far more effective means that you may already have in your household! Such impressive piece of literature will also tell you how to tell stains apart from “stains”, and what to do about the latter! It does carry a small price tag, and you can order it by logging on at:   http://www.mbstone.com/literature/literature.htm.   It's available in pay-per-download format and it's much cheaper than any kit on the market! Not to mention the little and much needed support you'd be giving to the cause – your cause - since every single penny of the cost of the article will be used to support it.
