48g over-zealous cleaning

[Jeff_Birt]

I ran into the alcohol issue on a TRS-80 PC-2 printer/cassette interface today (Sharp CE-150). The TRS-80 version is painted flat black. I wiped it down with Formula 409 but there were a few stubborn spots. Not being sure if it was sticky goo or the result of the NiCad battery out gassing. I tried a quick wipe with alcohol on the back, a.k.a. an inconspicuous area, but it was also removing the flat black paint. It was not sticky goo but from the corroding battery pack. At least the PCB and innards were unscathed.
