I'm not necessarily advocating this, but I heard of a novel (though not new) cleaning method last Summer when I was visiting the VintageTek museum in Portland, OR.

My Dad was explaining how they cleaned oscilloscopes when they came in for service back in the day. They were all built point-to-point, discrete components, tubes and all. He asked me how I thought they cleaned them. I suggested the usual - brushes, cloths dampened with water or solvents, etc.

He said no; that was way too slow to keep up with the volume. The eventual solution was to open the scopes up, and remove the tubes. Any paper caps were covered with condoms, and the insides of the scope were hosed off with soapy and then clear water. They were then dried in a pizza oven.

The only change I would make would be to rinse liberally with distilled water, to avoid leaving deposits that might be conductive. After dumping a cup of coffer in my running laptop, I looked up what to do on the internet. I followed the directions, which were to:

1. Turn it off immediately. I'd already done that.

2. Remove battery.

3. Rinse in distilled water. Really? Yup.

4. Repeat using fresh distilled water until you're pretty sure you got it all. I repeated until I couldn't smell coffee two times.

5. Drain as well as possible.

6. Allow to dry THOROUGHLY. I left it on an air conditioning vent in several orientations for two days. Worked fine afterwords.
Yeah, thats exactly what I feel like doing, but.... - ABliss 11:31:35 04/03/14 (0)
I think I will take the slow way. Besides, my oven is not quite big enough. :)

AB.
