I use IPA here at work for that purpose, but I was assuming John wouldn't have any handy. At the moment it's not just a simple matter of strolling out to the shop to get stuff. (A pharmacist might have some, I guess).

I was thinking maybe something like nail varnish remover or some other common household solvent. It has to be something which won't lift the screen printing or the red solder-resist (come to think of it, nail varnish remover probably will).
