If no luck try same with acetone.

Except that as I pointed out elsewhere here, the keys probably are not
actually ivory but some kind of plastic instead, unless it's an old or
valuable instrument. Most piano makers stopped using ivory quite some
time ago.

Acetone is generally not kind to plastics. (Great cleaner otherwise.)
