I've got a folding coin that the rubber band has perished in, leaving hardened rubber inside its groove. I've tried scraping it out and it will take a lot of work to clean the groove out. So how else can I get the rubber 'dissolved' without affecting the coin colour? The coin is a New Zealand $1, basically steel with some golden-coloured plating over top of it.

Also, how do you keep spare rubber bands perishing? With balloons they are best stored in cool dark environment. So my feeling is this would work with the bands as well.
Information, please!
The presentation makes the magic.

Acetone will clean the remaining rubber out magicol.
just soak the coin a few minutes and finish scraping it out.
as far as the bands keep them in a air tight bag in the refrigerator.
that's the way I keep my balloons and they last a long time.

Be careful what you use to clean the groove. If you use a knife point or paperclip, you can scratch the inside which will cause an abrasive spot that will wear the bands out quicker and it will always break in the same spot. Use a toothpick or some other softer point. Good luck.

Fingernail polish remover is acetone for those that can't find it in the hardware stores.
In some US states and International Countries acetone is illegal. Yet still sold as FNP remover.

Just make sure it says acetone on the ingredients. There are several acetone free versions now.

Dental floss can be very helpful.

I sometimes use sewing needles when this happens.

Another vote for dental floss. It may be easier to have someone hold the coin whilst you give it a floss - you can exert more pressure.

Just to add, don't forget to clean the inner fold edges. They will collect a minor film of grime, grease, oil (or whatever it is that collects). The safest way is just scratch down the edges with your thumbnail for a minute or so. Don't be tempted to use even a fine grade sandpaper - it's far too abrasive.

I think the perfect combination would be to soak it in acetone, then use dental floss to pick the excess remains away. Smile

I will try this the next time this happens to one of my fo***ng quarters or fli**er coins.
