I have always not been very fond of WD 40 in its ability to break rusted
nuts or bolts free.
I have found it to be great for drying out wires or engine stuff that got
wet. I don't know if
more displaces the water than dries it but it works. Plus my wife uses it to
remove
Crayon off the picnic tables at the cider mill. Every year kids end up
writing and drawing
on them. I used this tip and it took the crayon off of our cabinet door in
our Westy. One
of my kids this past summer decided to write Hi Dad with a yellow
crayon. None
of them would admit to it as usual...
