- WD-40 began in a military lab in 1953. The mission to prevent rust and corrosion on Atlas missiles during the Cold War.
Engineers needed something that could displace water (hence the “WD” for Water Displacement) and protect the metal components inside these high-tech rockets.
It took 40 tries to get the formula right, and that’s why it’s called WD-40. (from Kim Komando)
