Permatex RTV Silicone Dissolver features a patented formula that dissolves and completely removes RTV silicone residue in only a matter of minutes. The gel-like formula allows for removal in hard to reach places and is also safe for use on aluminum and other surfaces.  Grinding wheels, metal scrapers, and chisels can severely damage flanges and ultimately compromise the potential for a good seal. This silicone dissolver safely removes all silicone gaskets, including Permatex® the Right Stuff® gasket maker residue and all other silicones. Simply spread on the surface and let stand for several minutes to soften gasket material (allow longer contact time for thick layers) and wipe material with a clean rag or safely scrape from surface with the Permatex® SaferScraper. Note: Does not work on non-silicone gasket residue.
