WD-40 is a household name. It’s a popular product in houses, garages and machine shops due to its ability to clean, protect and lubricate just about anything with metal parts. It was developed in 1953 by Norm Larsen and its full name is “Water Displacement, 40th formula.” It was designed to repel water and prevent corrosion on the Atlas space rocket, but gained mass appeal when it was found to have a multitude of other uses.
While most people are probably familiar with spraying WD-40 into door hinges and other metallic objects to prevent rust, few people realize that it also works as a pretty handy cleaning agent, taking down fingerprints, sticker residue, scuff marks and even crayon.
