Add another fan for the nitrile gloves list. I've found they last way better than latex.
I'm pretty big on keeping exposure to petroleum solvents to a minimum, so I like to use cooking oil as a solvent on my hands. Loosens up the grease, and then some regular soap will take it away all right. Even solid white cooking fats will work okay (but take more time to loosen up than liquid oil).
Plus, an extra large can of Crisco makes a great conversation piece in the shop. "How much does it cost? Well, go grab that can and we'll discuss it..."
Never have tried the baby wipes; intend to go get a tub of 'em. Can't be too bad for skin, right?
I really try to keep all the harsh **** (MEK, solvent, brake cleaner) away from me; a lot of that kind of stuff is really bad on liver and kidneys, and will build up in the body over time.
I didn't care so much about all this in the past, but seeing how much trouble my Dad has with trying to keep his fingernails attached (they pull loose real easy) after many years of chemical exposure really knocked the 'macho' outa' me on this score.
