Growing up around a shop of any kind, a marvelously cluttered place used by mechanics, builders and others to make and repair stuff, means understanding the value of that wondrous fluid in a can- WD-40.
It was created by Norm Larsen in 1953 to “repel water and prevent corrosion”, the 40 signifying his discovery of the formula on his 40th attempt.
Over 60 years later we're still discovering uses for that magical fluid in a can, because it does a heck of a lot more than just clean off grease or silence a squeaky hinge.
Was your car vandalized by an angry ex? Simply apply WD-40 to a rag and wipe that vandalism away without damaging your paintjob.
Sick of snow sticking to your shovel? Apply WD-40 to the shovel blade and watch that snow slip and slide off with ease.
