Did you know that the original WD40 formula is so closely guarded that the company never even filed for a patent?
The composition of this legendary lubricant is handwritten in a notebook alongside 39 failed attempts, hence the name WD40, and is kept in a bank in San Diego, California. None of the employees have ever seen it and never will.
As a result, in the 73 years since the formula was created, no one has been able to replicate it. This magical formula protects and maintains any mechanism in excellent condition. Rusty bolts and screws loosen easily without damage.
WD40 is used to clean any surface: metal, glass, plastic, or wood. Just spray it on, wipe the surface, and marvel at the results. And don't forget about rubber seals. The lubricant keeps them flexible, prevents cracks, and extends their lifespan. It removes any kind of dirt.
Door hinges stop squeaking, and spraying it on an old lock makes the key slide smoothly. This miracle lubricant can do everything, or almost everything.
