How to clean RCA inputs and outputs?


In the past few months I have purchased used audio equipment from AudioGone, AudioWeb, and eBay. All vintage from '70s & '80s. Almost all input and output jacks are covered with a dirty film, grunge, or slight corrosion, especially the unused RCA jacks. What is the best method and cleaner to safely use? Any suggestions would be appreciated. Thanks.

I also use the RCA jack cleaner tool that, Scott mentions above, along with contact cleaner that I got from Sonic Frontiers-- both the cleaner and tool seem to work well. Good Luck. Craig
Give those conections some vitiams !!!! Tea Tree Oil !!! You find it in the vitiam section at Walmart. A small bottle is around $ 4.00. It will amaze you, it cleans everything like new. I use it on the pins of new and old tubes. Really makes a difference you can hear. I clean all the connections in my system about every six months with this stuff.

Try it, you will like it!

Good Connections to everyone.
I like Caig ProGold from www.audioadvisor.com. Not only does it clean the contacts, it leaves a thin protective coating.
Go to home depot in the electrical section. They have some contact cleaner in a blue can. It is $6 and leaves no residue. Spray some on a towel and wipe away. It works great... You don't want products that leave a residue.. it attracts dirt.
