SOLVENTS of CHOICE: PART2a When the Sticking's Done...
So you've successfully re-affixed your A) mic's grill cloth; B) corner of your amp's Tolex covering; C) kitchen counter top using an aerosol contact cement as described in PART2. GOOD! But wait... even though you were careful to direct the short blast of spray toward the inside of the grill only, it seems the unintended over-spray has deposited a dusting of schmutz on the inner bezel of the grill where it fits over the flange of the shell's body and on the exterior of the grill's frontal surface as well. You might guess that by snapping the grill back onto the mic's body with a layer of spray glue sandwiched between them would give you an object lesson in the meaning of the label "contact cement". You'd be right... I've worked on harpmics that have fallen prey to this sticky dilemma on several occasions. The consequences can be quite annoying -or even more serious, quite destructive.
MIC MORSEL: Keep a multi-tasking / non-destructive cleaner handy for such clean-up chores, one that's good at breaking-down the glue's bonding ability but won't melt the finish off your mic. The two I've gotten the most mileage out of are GOO GONE and CITRI-SOLV. They each have their specialties beyond removing a variety of nasty adhesives as well. GOO GONE is especially good at dealing with what I'd call "heel marks" -the black rubbery marks that seem to collect during the wear and tear of musical combat. CITRI-SOLV works on many types of tape residue. A small dose on a bit of terrycloth rag can work wonders. WARNING: DO NOT use an actual 'solvent' for this type of mission. Please, NO Lacquer thinner, Acetone, Naptha, Xylene (nasty stuff), or anything labelled 'paint remover'. The mic you save might be your own...
