What solution to clean silver and gold contacts?


Hello!

          I am looking for a product to use to clean contacts in my audio system. Contacts are mostly gold plated, but some of them are pure silver on pure silver.
         I do not want anything that leaves any kind of residue / contact enhancement product. I read on forums that some members claim these products improve the sound at first, but later degrade it. So in the end, they removed all of the contact enhancement product from the actual contact.
         Right now I am mostly leaning towards using pure ethanol alcohol, as I think all of it would evaporate.
         Thanks in advance for all of your advices.

Tarn-X will cause pitting of the object's surface. These surface defects will act like a sponge and more readily absorb tarnish-producing gases and moisture. The object will eventually require professional polishing to restore the original finish. Tarn-X is made up of acidified thiourea (a known carcinogen).    http://www.hermansilver.com/tarn-x.htm
@dweller - My post was simply a quote, from the cited article(close to the end). Happy listening!
Unless you’re living in a Sulfur-rich environment(ie: around volcanoes/chicken coops/sewage treatment plants), you needn’t worry about sulfites forming in, "a matter of minutes"! https://www.powellind.com/sites/downloads/ProductAssets/01.4TB.080%20Switchgear%20in%20a%20Sulphur%2...Various conductivities/causes, concerning oxides/sulfides, discussed here: https://forum.audiogon.com/discussions/dielectric-grease-on-connection-ends/post?postid=1381403#1381... BTW: What stanleylocke and williewonka said, +1(each) 
BTW: Silver WILL form an oxide layer, as long as the, "ambient conditions" are below 195 degrees Celsius(almost twice boiling), and - the atmosphere contains Oxygen: https://study.com/academy/lesson/silver-oxide-formula-decomposition-formation.html
