Drivewaysonly provided some fine advice using 0000 steel wool. I've never tried using the wool dry, but I don't see how it could hurt. It would most def. make the wool last longer because it won't rust as quickly. I havnt tried the non-rusting bronze still wool, yet. I think Titan Labs, the maker of GG4, makes a product called Oil Flo, which should work well in removing silicon. Other then that, a scraper will be your best bet, along with your regular cleaning solution. Be careful.
