Use Gojo which smeels nice and does a good job, but really like the "jello" type hand cleaner that comes in a can (cant remember the name, Crappy tire and other places sell it, white jelly stuff the liquifies on your hand when it warms up). Stuff works great, needs no water (which I dont have in the garage) and I can use it over and over to keep the crud off my hands. If I come in and my hands are dirty I just use dish soap. not as good but there and handy. When I worked for Xerox they had a tube we used to use, which came out like tooth paste and you rubbed on your hands. Would dry and left a layer of "protection" on your hands. Even working with toner (plasticized carbon) and getting really filthy, a bit of water and your hands were perfectly clean.
