Hello to the group. This would be my first question, but I wanted to also take the opportunity to say hi and am looking forward to a prosperous future with you to both assist and ease the issues we face in this very complicated but fascinating industry

A rare granite was installed and sealed using an impregnator 3 years ago. About 3 days to a week later  the silicone made its way to the surface and discolored the granite top. I have used a poultice mixed with Methelyne Chloride last year but with no result. I have removed a granite top and was able to remove the stain once I removed the silicone in back. The other tops are difficult to remove without breaking. Is there a new solution?
