cleaning your spade connectors

Your going to think I am crazy but a friend of mine just said the other day that he had a pair of Cardas Quadlink 5c's that had oxidation on them and he used toothpaste on them and it took it all off. They look like brand new?? I Tried it myself and it worked?? They look new? Give it a try it's not going to hurt anything. Good luck. let us know.
Here is a link to a thread here some time ago on the same thing.
The person who asked the same question tried the tooth paste and said it worked for him also. there are also some other godd suggestions there. Good luck let us know.

gladly saying - ain't no need to swallow toothpaste:-)

There is a metal cleaner called "Flitz".I have used it.Flitz is simply amazing!!!!!!!!

defenitely 'flitz' it! every few monthes ,disconnect your entire system and start polishing your ac cords 3 pins ,and just about every connectores in your system. you'll be amazed to how much s*** and dark goo are on your coneectors. try and you'll be flitzed over....

Since the writer didn't state the metallurgy of the connectors, I'd take all forgoing advice w/ a grain. Nobody advised to rinse well with purified water. Most commercial metal polishes - if you're lucky enough to use one that doesn't contain abrasives - contain a light oil to retard corrosion. They're for making stuff shiny like tea kettles and pots and pans. Bite the bullet and get de-oxit or kontact...

Ketchup works quite well on naked copper, but... rinse well.
