Time for a helpful household hint, I think. I shared this one with someone earlier today.
To get the smell off your hands after slicing and dicing onions, rub your hands all over with a stainless steel spoon under cold running water. I believe there is some magical alchemy involved. Well, at least some basic chemistry. Anyway. It's supposed to work also with garlic and fish odors.
I do have a few domestic bones in my body. Not many, but there are some in there!
