How can I clean the contacts on an old organ?
Our unit in college found a free organ on craigslist. It mostly works, except for a few keys that are iffy when played. Meaning, some play and others do not all the time.
We've taken it apart, and the contacts are a spring and bar type of connection. I'm wondering how to make them work like new.

I used pencil erasers on an old Farfisa, a Korg DW8000,and a Roland stick (can't remember the model #)...worked like a charm... Brrrrright and shiny! And every single key wokred. The Farfisa was a 60 some key board, almost every other key was dead prior...DW8000, about a 1/3, the Roland had about 4 keys that actually worked (beer spill and closeting for about a year...rebuilt for the friend who trashed it in the first place) A lesson learned from the contact brushes on Aurora HO slot cars in the early 1970s.... wipe a bit of pot cleaner on them after wards with a low lint Q-Tip. In fact, I plan on getting the DW8K working again once I find its power cord. I'm sure I'll have to polish at least a few contacts. Showing my age? lol

I'd choose both, but I can't so it goes to seandogue.
Heck...i don't need the "kudos".. give it to someone else if they want it :)
but please do give the eraser a try...it works amazingly well on tarnished silver or copper contacts without the harsh effects of a more robust abrasive

I'd try emery paper -- a very, very fine sandpaper, usually on a mylar backing -- to polish the contact areas. You may also need to bend the spring a bit. Have fun -- you can now claim that you are finally Well Organized!
