I am restoring/rebuilding a vintage transmitter. The components such as
wafer switches and variable capacitors are good quality ceramic but are
very dirty.
Does anyone have advice on the best ways to clean these?.

I bought one of the Ultrasonic Cleaners from Aldi that were mentioned a few
days ago.
Actually 550ml, not 750ml as advertised. £20 in round figures.
Available liquid depth is 35mm.
Tank is stainless steel with a plastic removable inner basket.
50w, 230vAC
Works a treat with warm water & a dash of Fairy liquid.
Tried it on an old ceramic-based knife switch. Cleaned up the ceramic
beautifully.
The brass wasn't so impressive - removed the dust & grime, but obviously had
little effect on the surface oxidation.
