Oh you love it when your husband changes you car’s oil instead of bringing it in for service. It’s more economical! But he hates it when it comes to getting the grease off his hands because hand soap alone does not cut it, right? To get rid of the grease easily, have him rub vegetable shortening onto his hands prior to washing them. The oil in the shortening dissolves the car grease and loosens its bond to the skin so it can be rinsed off in a snap.
