JUST A THOUGHT...As a mechanic my hands dry and get pretty rufff from washing them 20 times a day ... in the winter I use a lotion called liquid glove ... you can buy it in car stores or automotive sites.Its a silicone base that seeels the hands and protects .When it comes to washing off greese and dirt comes off so much easier and you dont need to use the drying agents and pumice soaps.
