Cartier

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... ...  

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

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... 

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.

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