I read about some people using an ultrasonic cleaner to clean variable condensers. I bought one, the kind used for jewelry pieces. Its container is big enough to handle a large, 3 section tuning condenser. You fill it with hot water and a little dish soap, put in your condenser, turn it on, and wait a while. After a half hour or so you have a nice clean condenser. Just be sure to rinse it well, and then dry it well at the end of the process, and lubricate all the bearings for the shaft.
