Here is a thread on a similar question ‚- with two answers for finished and unfinished wood:
Thank you for the suggestions but this doesn't answer my question because my wooden tabletop is "finished". The only response I found was for unfinished wood. Could we try again? Many Thanks!
rub mayonnaise on it, leave on overnight and rub off - voila - stain gone!
Annie is right. Mayonnaise works great. You might also try car wax if that doesn't work.
