What does everybody use to clean your gimmick coins?

Lemon juice has worked better for me than anything, leave it in there over night, sparkles the next day. I've tried all the tomato things but nothing works better than lemon juice. And a lemon cloth works good also.

I've never cleaned gimmicked coins, but I have cleaned regular coins, and at least for those, Diet Coke works wonders.

I use Easy Off "BAM" cleaner.

Put some in a glass bowl and drop in the coin for just a few seconds then rinse with water and dry it off.

It really makes them sparkle and does not remove any metal so the parts fit perfectly. I have used it on my English pennies, silver dollars, niclkes, pennies, and even brass items with no ill effects.

Another great side effect is that the milled edges are clean too, no polish residue making them dark.

Twist

I tried that, didn't work at all for me. Do you use warm or cold coke?

vinegar and salt

I warn against that just because it stinks. But it does cleans coins alright. I really want to try some BAM but my coins are clean at the moment so I'll wait.
