Greetings,

Here is a thread that WD40 was talked about in the past. You can use 
this date to go back and view all the comments. Apparently there was a 
prior thread on the same subject even further back.

Hello List

    Possibly one of the sources of the idea that WD-40 contains water is my
preservation page.  The reason I wrote this was personal experience.  When I
was starting out in the business, I bought a gallon can of WD-40 at the
hardware store.  I poured it into a glass container to treat some
meteorites.  In the bottom, sitting in an immiscible layer was something
that sure looked like water to me.  I didn't analyzed the layer, but when I
heard that WD-40 contained water, I was convinced.
