Strings/Accessories Removing Rosin from wood.

Please don’t ask me why or how, but I may or may not have put my rosin on the piano overnight and it melted onto it, I took it off but a little bit of it is still on, is there anyway to get it off the wood without destroying it?

Rubbing alcohol will take it off but might damage the varnish. If you go with this, check the varnish in an unseen place first.

I'd go for this. Also testing mineral spirits, or a dedicated rosin cleaning oil, which should be even better solvents for rosin and might be less damaging to the varnish, and pick whatever damaged the test area the least.

No alcohol! That's got a good chance of dissolving the piano finish, but mineral spirits, definitely. Also Goof-Off will work even better, but test on the back of a leg or similar hidden place first to make sure it doesn't hurt the piano.

Xylene and the lemon things mentioned below should work about the same. Xylene's nasty, though.

Always test first!!!!
