If you want to be very delicate, use isopropanol (isopropyl alcohol). If you suspect more resistant organic deposits, toluene is useful. There are also household 'cream' cleaners that are effective, but you do need to wash off as the residue may be a bit too aggressive. I do not recommend cola or tomato sauce! I can't help with your PC, other than the obvious suggestion, to replace the finger-gasket with a better quality one. -- OOO - Own Opinions Only.
