WD-40

WD-40 is a penetrating oil manufactured by the WD-40 Company based in San Diego, California. Its formula was invented for the Rocket Chemical Company in 1953, and it became available as a commercial product in 1958. It acts as a lubricant, rust preventive, penetrant and moisture displacer.

There are specialized products that perform better than WD-40 in many of these uses, but WD-40's flexibility has given it fame as a jack of all trades.
