Olive oil for cleaning grease from hands
Today I did some work that got chain grease on my hands. As I have done for 50 years after working on bikes and cars, I started to reach for some detergent to wash it off. Then, there on the sideboard at the sink, I saw the olive oil I use on salads. My chemistry training from 45 years ago came to mind: "like dissolves like". I put a teaspoon of olive oil on and rubbed a bit and -bingo- clean hands. No elbow grease, no brushes, just grease gone on a paper towel. The olive oil came off with some really mild hand soap.
I'm feeling a little abashed that only now did this idea ever occur to me. Any cooking oil would probably do the same. Really easy on the skin.
