Try using the stuff. The argument on this always comes down to two groups of
1) Those that have experience using the product say it is corrosive or gums
up the works.
2) Those that quote the manufactures promotional materials and say it is a
degreaser and a lubricant. Something strike you wrong with that WD-40
advertising BS? Pehaps it degreases it's own lubricant?
Read some forums on people trying it on guns, carparts and other metal
parts. Most of them are disgusted with it's results contrary to what the
company, claiming they have never changed the formula since 1955, say. They
used to claim Stoddard Solvent and now claim WD-40 contains none. The list
The product only provides temporary lubrication while it is wet. When all
the solvents dry out the degreased gum remains of the former lubrication
seizes up any parts that move with a shellac like-substance. The hygroscopic
feature absorbs moisture and leaves it behind to further damage the
degreased parts starting to lose their finishes.
People swear by the product for lubrication and reapply it every few weeks
or months. There is a reason for that.
Utter nonsense, again.
50 years ago it was Stoddard solvent (think kerosene-like hydrocarbon)
and its latest MSDS is only a slight difference--I looked it up just
within the last couple months on another thread and posted both the MSDS
and the links to the universal chemical code data sheets.

To the WD40 users. 50 years ago WD40 was corrosive and has not
improved yet. Just leave a shiny chrome thing in it overnight and look
at it in the morning.
