WD-40 is widely misunderstood. I suppose that, once the misunderstanding became 
wide spread, the makers advertised to 
take advantage of it.

"WD" stands for "water displacement" and "40" is the number of the formula 
tried which finally worked. It was designed 
to displace moisture and protect surfaces from rust. Although it does contain a 
light lubricant, it doesn't last long in 
actual lubrication uses. Nor, as this tests shows, is it particularly effective 
in loosening rusted threads.

Put what a wonderful product to have people believe in! Use it, and the squeak 
disappears, only to soon reappear, and 
require more application of the product.

If one needs a spray lubricant, there are lubricant sprays based on lithium 
grease, Teflon, etc. that are far superior.

Thanks! Good to know.
