removing melting rubber from metal?
Hi All, I have an EP-1 eprom programmer from BP Microsystems. The rubber feet melted. It was in my closet. I have no clue how it got that hot, or if they are just some composition for them to melt. My question is how do I clean this up? Acetone, paint thinner? I scraped off the feet, so there is just a few 'streams' of melted rubber down the sides, and a bit that somehow got inside (also on the side, not on the electronics). Just looking for some ideas before I start applying chemicals... Thanks, Kelly
