This sounds crazy, but grease takes out grease. My father was an automobile mechanic. My mother would put plain Criso shortening on the grease spots, then washed normally. It worked. She used the Crisco on any type of grease spot, such as cooking grease. I continued to use the Crisco until products such as Shout came on the market. 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.
