My dad used to work for a company in the 80's called "Bruce" that makes hardwood floors, and he used to work under a machine that leaked hydraulic fluid like crazy...
He gave me a trick earlier this year that is fucking AMAZING. Anytime you have something that has grease, or oil, or anything just nasty... spray it down with WD-40, rinse it a few times, and run it through the wash, basically by itself or else it will release that grease all over your other clothes.
I have been working on cars for about 10 years now, and he just now told me this trick... I could have easily saved 100's of dollars in clothes.
haha thanks dad ^ could've got some new gear with that $
