Don't do it.
Although MS70 is merely a soap, it will destroy the nordic gold alloy almost instantaneously, leaving an ugly brownish hue to the metal, and if let sit on for more than a few seconds, the whole coin will turn almost brown, and then start to turn some pretty interesting hues of blue as well. I was trying to get off some fingerprints, and after using MS70, even the fingerprints were still visible afterwards.
So never use this product on nordic gold. What a strange alloy!

<< <i>Well, the coins sure did lose their collector value, but they're not gold. Nordic Gold is an alloy of copper, also used on Euro coins (see here). The coins I experimented on were Polish 2 zloty commemorative coins that had some ugly stains on them which I wanted to remove if possible. At the same time, I treated a few others having only some fingerprints on them, in order to clean them up. I've used MS70 successfully on dirty but uncirculated silver and copper/nickel compounds, and thought it would work on nordic gold. My attempt failed, however.
Oh, ok.
