What Solvent Will Clean Silicone? | Hunker
17/3/2019· Rubbing it with sandpaper or an abrasive pad isn''t a good strategy because the caulk tends to form small balls that stick to each other and to the paper or pad. The best strategy is to soak the residue with more mineral spirits, alcohol or vinegar to further soften it and then scrape it with a pull scraper or sharp knife.

31/10/2017· You can buy a whole set of silicon carbide "sticks" in a variety of grits from eBay/china, green in color and maybe 1/2" x 1/4" x 6" in size for under a tenner. These are super friable (not particularly useful for grinding steel, directly) but great for creating lapping paste without buying 1+ lb bags of loose silicon carbide grit.
