Could anyone give me a bit of advice on looking after coin uniques please? After much use some of mine have become tarnished internally and externally. My thoughts are good old fashioned brasso to clean and then a spray of WD40 to protect both inside and outside?

If you use it a lot I would probably buy a new one.

Thanks Warren, I have three, they work perfectly and don't come cheap so buying new ones would be the last resort at the moment.

Brasso will not hurt it. Mas or Flitz works we also.

Why do you think cleaning it would effect how it works? Just wondering. I have had mine for about 20yrs and cleaned it I number of times with no effect to the working of the gimmick. I use Flitz and or coopers copper/metal cleaner. I do not use brasso because I do not like how it smells.

Thanks Mobius303, much appreciated. My only concern was whether using cleaners would damage the thin metal layers or not, with 20 years of experience you have answered that for me perfectly.

The kinds of things that are more likely to damage the coins are harsh chemicals and ones that are designed to break down glues (e.g. acetone) - as the CS might come apart. These cleaners are designed to be gentle, to not take of non-oxidized metals - otherwise they'd be terrible when used over time on door knobs, candlesticks, etc.

That said, a nice patina can be a beautiful look, too. You could certainly consider leaving it rather than polishing the coins back up. But you call, in the end.

Thanks tons of questions. It had gone beyond the nice patina look so polishing was definitely in order. Brasso to clean and some WD40 to protect seems to have done wonders to them and they look normal again.

Please DO NOT use brasso on coins. It is to harsh.

I recommend "Never-Dull". It cleans and leave a slight coating that preserves the finish.

To be clear, the "harshness" you're talking about is for large-scale wearing down, or from a collector's point of view?
A quick search online suggests that the formula for Brasso is different in the US and UK. So it might be OK for Bogbadger.

I suspect that using it once wouldn't be a problem, but using it repeatedly could be bad.

I'd also meant to point out that WD40 probably is a bad choice for "protection" - it's a bit oily, which isn't something you'd probably want on your coins (or a locking set), and it degrades some glues. It's probably OK here, but something else to consider in the future.

In the end, the tiny amount you used this time likely doesn't do any damage, but it's something to remember for next time.
