It sounds like an urban legend, but your friend here is stainless steel. You don't need to buy one of those $20 ovals of stainless steel, you can use your spatula or your spoon or, well, anything but a knife. Just clutch it between your hands while you scrub with soap and water, and let the water run from the tap over your hands. When you're done washing, your hands will be odor-free!
