Don't ask me how it happened, but I lined a walnut bowl with saran to
protect it from something, and the saran 'melted' onto the bowl. What
can I use to remove it?
I am no good at sanding etc, so that would have to go to a pro if
that's the only solution.
Thanks.

Not many details here-
Is it possible that heat or moisture caused the wrap to meld into
the finish?
If so, you'd have to use the appropriate solvent to dissolve some finish
and get the wrap out, then apply a new coat of finish.
Difficulty depends on what finish was used.
