d-limonene based solvent normally does it for me but you need to be careful due to delamination risks. Apply indirectly, using a nappy towel.
Other than that, an alcohol based spotter quite often sorts it out.
Whatever you use, try it indeirectly with a nappy towel first to check for colour transfer... if you get a strong transfer that way, treat and extract. Several light goes is better than one heavy one.
