Gotta disagree - WD40, for example, makes a great remover of tape residue, but.... it should be kept away from cracks/crevices to keep it from entering the equipment as it might bring something inside I didn't want. Capillary action will pull it in if it's too heavy an application. I've used it on all manner of electronic equipment with no detrimental effects. If I thought WD40 might create a problem, I'll use a PDS cleaning spray, again on a cloth/paper towel to gently apply it. I've never seen WD40 or the PDS line damage plastic or electronics. As with most things, moderation is the key.
I did a test in the calibration lab one day and found 409 cleaner leaves a surprisingly conductive film behind, but WD40, Windex, and several other cleaning/lubricating solutions did not. I was the high frequency guy in the lab, calibrating the equipment from 400mhz to 21ghz. It was easy to kill the calibration with the wrong cleaner in the connectors!! I got very good cleaning things with isopropyl alcohol and distilled water.
Take care,
Mike
