I've used diluted nail polish remover, immediately followed by a clean water wipe on various frames and never had a problem. Since it's only the residue you have left, you don't need much time to dissolve it. I take a soft cloth, apply a bit of water and then a bit of nail polish remover. I also have a second cloth already soaked in water. Then I take the polish remover cloth and briefly make circular swirls on the areas targeted. I follow with the clean water cloth, and then inspect the work to see if I need to do more. It may be over cautious, but as I've said, I've never run into problems with any finish. I've even used a similar technique on lacquer finished guitars with no ill effect.
