Dear Avital, WD-40 is a product that has many uses - see David's email - however - Wikipedia says -
WD-40 is the trademark of a widely-used penetrating oil (cleaner, lubricant and anti-corrosive solution) developed in 1953 by Norm Larsen, then working for the Rocket Chemical Company. It stands for "Water Displacement, 40th attempt" (see below). Its first industrial use was by Convair, which used WD-40 to protect the outer skin of the Atlas missile from rust and corrosion. The product became commercially available on store shelves in San Diego in 1958. WD-40's name comes straight out of Norm Larsen's lab book. Larsen was attempting to concoct a formula to prevent corrosion a task which is done by displacing water. His persistence paid off when he perfected the formula on his 40th try. [1] At one time there was for sale in Mexico a similar product called "WB-50" whose name apparently had no meaning other than to mark it as an alternative to WD-40. While its uses are many and varied, WD-40 should not be used as a general-purpose lubricant, as it dries out very quickly and collects dust. This can result in serious damage to machinery and equipment designed for use with heavy oils when they are lubricated with lightweight WD-40. Many handymen consider WD-40 and duct tape to be the two most important items in their toolbox. In The Duct Tape Guys' book "WD-40", they proclaim "Two rules get you through life: If it's stuck and it's not supposed to be, WD-40 it. If it's not stuck and it's supposed to be, duct tape it." It is especially helpful for taking apart metal objects (nuts and bolts) that have been exposed to the elements and are rusted together - such as ham radio antennas......
