Suppose you've been working on a bike, or indeed a car, your hands are covered in black dirty grease, and you don't have a specialised cleaning product around.

Take either a teaspoon of vegetable oil or a couple of sprays of WD-40 and rub well into and over your hands, before going to soap and water. The soap will dissolve the light oil while the oil dissolves the grease: it's much, much easier to get clean than with soap alone. Plus, you now smell of WD-40, which is well-known to be an aphrodisiac. Or anaphrodisiac. Whatever.
