How do you clean RCA connectors?

post #1 of 7
Thread Starter 
I am restoring an old amp that I have. The RCA connectors are all tarnished. I can use steel wool to clean up the outside of the jack. But how do you clean the inside of the female connector?

Don't do that, you may destroy the contact surface. Use antioxidant and cleaning fluid. Kontak and Deoxit are a little expensive but I think Radio Shack has something that will work.
Apply it on a pipe cleaner.

Thanks Anders

the radio shack contact cleaner is isopropyl alcohol. Will that deoxidize the surface?

What I have seen, isopropyl alcohol cleans dirt but not oxides. I have tried Kontak and it is effective but costs about $40. Besides, you can clean all other connections too and get a supply that will last a few years. There may be something cheaper that does the same job, but I have no suggestion.

DeOxit D5 does a superb job.

The Absolute Best! rca cleaner is the Signet rca cleaning tool, for both m/f rca's. It's back in production.

Try Music Direct @

Not only is this the Best!, it is actually the only rca cleaner that is even 1/2way decent.

Thank everybody. Got some Deoxit from Fry's for $9 last night. Big difference between treated connector and non-treated. Used pipe cleaner for cleaning the the inside. Don't know how it work but the Signet tools looks good. I'm going to order some today.
