eau de oil/gas.. how do you get rid of it???

[68gmsee]

Everytime I work on my vehicles, my wife remarks about my oily, gassy smelling clothes and it also lingers on my hands. She happens to smoke and I don't, so she doesn't complain, just remarks.

I usually use regular gojo and/or orange type cleaners but I can't seem to get all of the smell of my hands.. Any suggestions appreciated.. Please...
