Spray and wash or shout out,it works,
Dawn dishwashing detergent really scrub it with a toothbrush then add Clorox 2 for colored clothes scrub it into the spot and launder as usual.
you may want to soak in Oxi-Clean for 24 hours
I'd definitely try this degreaser product. This stuff works wonders! Pour a little on the stain, rub it in and let it sit a couple minutes then wash in a load. It works great!
