we all have read it, and experienced it a hundred times now (ok, almost 
all).
WD40 is only good to lubruicate the dust bin!

throw it away and get somthing useable.
there are mighty good lubricants (also in spray cans) out there, more
expensive of course. for most applications a simple thin oil or grease is 
worlds better
than a liter of WD40.

what is it good for as a water displacer? it vanishes after some time and 
the
water comes back... for loosening rusty screws there are also better 
quality sprays.

There should be a law for a warning label on WD40...
