Just make sure you use the plain white Crisco, not the yellow one, and make sure you put the Crisco only on the grease spots.
My Dad was a farmer and serviced his own tractors getting black grease on his overalls. Mom used a degeaser that would remove the grease but left the black stain so she would rub shortening on the black grease then wash using the degreaser to remove the shortening. If she didn't remove the black grease by this method and just washed the pants, the black stains were there forever. She did not like him going to town in stained-up clothes and always fussed at us for not dressing up just to go to the tractor parts store!
