WD-40 was origionally developed by the Rocket Chemicals Company in 1953. The name means
Wated Displacement 40 (40 is the formula number). It was first used in air and space applications such as the Atlas Missile. It is primarily made up of various
petrolium products and mineral spirits. Just like duct tape, it is a cornerstone of the average man's life. Also like duct tape, it has an uncountable number of uses. It is primarily used to lubricate and clean metal while also preventing
corrosion and rust.
WD-40 is easily recognized by its blue and yellow can with the red cap. It comes with a little red straw that is stuck into the nozzle to help direct the spray. Recently, to combat the inconvieniece of the straw, WD-40 released a new design with an attatched straw
on a hinge to increase ease of use.
If it is stuck, tight, rusty or dirty, use some WD-40 on it. It is the opposite of
duct tape in that it makes things
unstuck. Like duct tape, it is cheap and avaliable everywhere. It is a must for the
handyman.
