What is the main ingredient of WD-40 ?
Before you read to the end, does anybody know what the main ingredient of WD-40 is? 
Don’t lie and don’t cheat. WD-40.
Who knew; I had a neighbor 
who bought a new pickup. I got up very early one Sunday morning and 
saw that someone had spray painted red all around the sides of this beige 
truck (for some unknown reason). I went over, woke him up, and told 
him the bad news. He was very upset and was trying to figure out what 
to do…. probably nothing until Monday morning, since nothing was open. Another 
neighbor came out and told him to get his WD-40 and clean it off. It 
removed the unwanted paint beautifully and did not harm his paint job that 
was on the truck. I’m impressed!
WD-40 who knew? ‘Water 
Displacement #40′. The product began from a search for a rust preventative 
solvent and degreaser to protect missile parts. WD-40 was created in 
1953 by three technicians at the San Diego Rocket Chemical Company. Its 
name comes from the project that was to find a ‘water displacement’ compound.. 
They were successful with the fortieth formulation, thus WD-40. The Convair Company bought it in bulk to protect their atlas missile parts.
Ken 
East (one of the original founders) says there is nothing in WD-40 that would 
hurt you… When you read the ‘shower door’ part, try it. It’s the first thing that has ever cleaned that spotty shower door. If yours
is plastic, it works just as well as glass. It’s a miracle! Then try it on your stove top …. Viola! It’s now shinier than it’s ever been. You’ll be amazed.
