Hi all,The copper binding posts on my M60s are tarnished as hell. What's the best method to clean them? Also, what do you recomend to slow future tarnishing?
Thanks

I don't know is you ever done a "valve job" on a car, but the final seating of the new valve to the new seat is lapping. I use the same approach with electric contacts (eg: switch points, spade connectors, even tube into sockets).First for spade connections, clean the spades and contacts with a very fine straight fingernail file. Keep the contact surface of the file and the connector as flat as possible while filing. Avoid creating high points. For the spades I use a lapping board (since I have one). What you can use is a sheet of crocus cloth (or the finest sandpaper you can buy) and a little contact cleaner. Place the crocus cloth on a smooth, heavy, and STRAIGHT good sized board or metal (eg: 8" x 11"). Secure the surface. Apply some cleaner to friction area. Now, rotate the spade on the crocus cloth as smooth and even as possible. Both sides, if possible. Clean and dry.
Take a little contact cleaner (De-OXIT, Cramolin, whatever) and apply it to the spade. Twist the post down so that it just touches the inserted spade. Rotate spade. Tighten just a little more, rotate spade. The idea is to make as much clean contact area between the spade and the lug. More good surface area contact, the more current can pass and the less trouble with bad connection later.
Good luck!

I used 120 grit wet/dry sandpaper on the spades then coated them with the Pro Gold. They look good, I have good contact on the binding post, they seem to be darkening on the outside. I coated the inner surface with Pro Gold, will that protect them?
I think that with Pro Gold & if the terminal makes a good, tight contact it should help keep oxidation to a minimum.
Brass wool (just like steel wool only made of brass). You can get it at your local hardware store. Then, after that, apply detoxit.
I just use a little deoxit and a rag. Seems to me Bill told me that once connected, no further oxidation takes place at the actual connecting point of the cable and post.
The posts are very dark on the outside, I used some progold on the posts and spades. Is Deoxit superior to Pro Gold or just another version?
I think progold has additional additives than straight deoxit, but I am not sure.
Wiping the lugs with deoxit doesn't totally remove all the tarnish, but it does seem to clean them up enough for me to forget about it. The important part...the posts and connecting points have always been shiny because of it being closed tight all the time.
