i am a bit confused about contact cleaner.
what does contact cleaner do to electrical surfaces?
how does it clean connector edges better than just wiping them off with a rag?
do you have to unconnect connectors before cleaning them with contact cleaner or can you clean them by just spraying them in situ.
have you ever repaired anything with it? or is it just for keeping things looking tidy?
