I regularly get grease on my jerseys when I put my bike in the car and take it out (I have no bike rack - have to wrestle it in and out of the boot). Tried everything - sugar soap, dish detergent etc. to no avail. Then found this stuff at LBS. It truly is a miracle at getting grease out, and works well on hands also, and no chemicals or petroleum based products. Excellent!
