My worst "shampoo" was with a gallon of gear oil--HATE that skunky smelling crap!..motor oil and ATF,hydraulic fluid at least donr stink that bad,and are easier to get off of you...
I've used Lestoil,or Dawn liquid dish detergent and Arm & Hammer baking soda to wash off oil spills,the baking soda works as an abrasive and also cleanses and deoderizes the smell better than soap alone...I use it when I get diesel fuel on myself,which also has a nauseating smell....
When I had a gallon of school bus yellow paint I mixed at work fly out of the paint shaker one day and smack me in the face ,and douse me with the whole gallon in my eyes and hair,I used Lestoil,fingernail polish remover (acetone) and just about everything in the closet to try and wash it out!--I succeeded in getting MOST of it out,but some of it had dried,so I had to cut most of my hair off,and use SOS steel wool pads to rub off the rest from my skin--I looked like a peeled lobster for a few weeks...(screwed my eyes up permanently too,but I never got a workmans comp case check out ot the ordeal)....
Anti-freeze dont bother me as bad as oil or ATF does--its slimy and gross,but it dont stink at least...water washes it off pretty good without any soaps,etc...
