This is not strictly a compact Mac question but there may be some fine points particular to them and similar age electronics.
Up 'til now I've been cleaning boards with IPA and a toothbrush, but I finally purchased an ultrasonic cleaner. I'm tested using diluted Stens 770-100 Ultrasonic Cleaning Solution on a couple of Mac Plus boards. I washed for about 4 minutes at 125 F. Then rinsed with distilled water followed by blow dryer on warm alternating with compressed air to blow the water from under the chips, then dry overnight. I haven't tested them yet, but they look great
However, some of my older boards have paper labels and stickers (e.g. on EPROMS). Should I remove these and re-attach after cleaning? It seems like they might clean right off otherwise.
Any other tips for cleaning 30-50-ish year old boards particularly?
