My wife get excellent results from spraying a little bit of oven cleaner on the spot and then wash immediately afterward. Don't let it sit too long. Oven cleaner contains tart and it could do some serious damage. You may even want to test for a time on the inside of the cuff or something before you try it just to trademark sure it won't hurt the jacket.

Squeeze a lemon on the grease then wash as usual
