Remove Tarnish from Silver

I noticed this thinking of a way to renew XLR's on cables that become affected after aging a while.

In the schools we have cables running from mixers and some are old and out of date should be replaced I'm thinking the cable's might be salvageable ?

Based on what you guy's are saying.

I did consider what Nigel said about the WD40 though.

What has that got to do with silver?, you surely don't have silver cabling

Do this with a gold contact and you wear away the thin gold coating.

You can't burnish contacts inside switches or assemblies. You use gold because it doesn't oxidize in the first place and never have to worry about it in any reasonable life span of use.

I have a 1950's era Selmer Paris clarinet with silver plated keys. After seeing how fast they tarnish, I'll stick with gold plated stuff for my electronics work.

as the clarinet crossed 59 years almost, perhaps a golden treat appears apt !!!

Sweaty fingers on keys, what do you expect?.

speakerguy79 · 22nd September 2009, 04:42 PM

It's actually pretty uniform over all the surface of the keys, not just where the fingers hit 'em. Still a great clarinet though.

Silver trays and teapots tarnish just by looking at them.

I don't have a great many silver teapots or trays!

In fact, I don't think I've got a single silver article?.

I think I had to many beers that night.

What was I thinking.

Maybe safer for the WD40.......... rinse Push-Pull rinse and repeat.....

But if the reason of using Gold is corroding then please tell me how do the wires corrode while they are inside of the package of the IC or the transidtor??

They don't. You usually see gold plated external connectors, especially in the audiofile realm of things.

They use copper wire internally in chips.
