Hi everyone, Any body know how to remove these stains? ;it always appears and developed with (Vermiel; silver plated with gold) material, like this tank here: Thanks a lot in advance... ...  

Do not use any kind of polish!

All polishes contain abrasive and will remove the thin layer of gold. You could try asking Cartier if they recommend anything. I think it's better to have the discolored gold than to have the silver show through which will turn black. Best, Martin

If it bothers you, you could try dipping or dabbing it with some e-z-est coin cleaner...

It is a non abrasive way to remove tarnish/toning from old gold and silver coins. I use it to clean silver dollars, and I used it to brighten a gold double eagle once that had some darkened parts from the copper in the alloy. I have not tried it on vermei... 

Gold layer is gone there

The dark is silver reaction with your skin/transpiration. Most probably silversulfide. Gold is inert. So either you polish it with silver cloth, leave it as it is or have gold layer replaced. You could even try putting a gold leaf to try it yourself.

Hope not , will try the safest ways to remove it ;otherwise I will send it to Cartier

But I heared that Cartier no more provide service to these Must watches, I'm not sure of that . Thanks for your comment.
