The main ingredient in goo-gone is acetone.


No it's not. It's an oil-based cleaner (i.e. petroleum distillates). As I recall, the older versions used xylene, but the current SDS says oil.

The main cleaner is d-limonene, a pretty harsh solvent. I would stick with using xylene, higher purity and safer for coins. It's your best bet for removing non-polar residues.

Thanks everybody.

I just picked up what I believe is an uncirculated 1972 TII Ike with tape residue. The seller suggested using Goo Gone to remove the residue. I had never heard of this and don't plan to use it but I was interested to find out if anyone else had used it.

When dealing with ANY type of residue, always follow the Polarity Ladder:

1) distilled or deionized water
2) acetone (do not use fingernail polish remover)
3) xylene


Thad, I have a question on your polarity ladder...

Why start with distilled water?

What can be removed with water that cannot be as efficiently removed with acetone?

Water is the most polar, cheapest and most easily available solvent. In chemistry, "like dissolves like", if the residue is polar in character, it will be easily removed with best solvent in the world. Why start with more expensive acetone? Water may even do a better job in many cases.
