Another extremely effective product I have found is Caig Laboratories'
DeoxIT spray.  Not only does it clean but it also somehow helps
conductivity.  I've used it on everything from key contacts to
drawbars on Hammond organs, to even the battery contact points inside
flashlights.  (Brighter light is the result, amazingly.)

Normally I am quite skeptical at product claims, but using this one
has sold me on it for life.  It beats all chemical type cleaners
I have ever used.  Relatively 'safe' (is anything?) formula as well.

Expensive at $10 to $15 USD per can, but a little goes a long way.
Also very, very good for the myriad of plugs and connectors on modern
electronic organs.
