Relay Cleaning

[Keithpgdrb]

I need to clean the protective relay in my vintage amp. I have read many threads about burnishing the contacts, as well as just replacing the relay.

I recall having seen one thread that describes cleaning the relay with alcohol. I have some 99% isopropyl. I do not believe this leaves any residue. would this be acceptable to try? or should I just lightly burnish and be done.

who can offer some advice. I'm not replacing it at this time. unless I break it. I'll have to try to find a replacement part for it as well, so forget it.

A little Progold (or similar) contact cleaner works well. It'll clean and lubricate it. The isopropyl alcohol will clean it, but won't lubricate. As for burnishing, I usually won't unless oxidation is preventing it from working. Not the presence of oxidation, but when it gets to where the thing won't work.
