WD-40 bursts into flames lubricating fan!
Dan Horton of Ocean Springs, Miss., was lubricating a wall fan with WD-40 in November  1988 when the can touched a live wire. The container burst into flames, burning Horton's    
18-month-old daughter Lauren.



WD-40 explodes touching amp meter! 
In Jackson, Miss. William Sharp was    spraying a speedometer cable in his truck   when the can touched an amp meter. The       can exploded, trapping his wife Susie --     
who survived--in the flaming cab.
Firearms - you should never use WD-40 to clean or maintain firearms.                               
It's hygroscopic and will attract moisture to the firearm which will result in rust.

Drive chains of any type - because WD-40 isn't a lubricant it really will not work 
well on Drive chains of any type.

Gears of any type - WD-40 doesn't have enough lubrication affect to be useful 
on any type of gearing only specified gear lubricants should be used.

Never use WD-40 on door hinges or anything you want to keep clean. It attracts 
dirt and dust. It will turn your hinge pins black.

WD-40 will ruin a bike chain and the gears wear out quicker. It washes the dirt in,                                     
the dirt acts as an abrasive and not a lubricant.

​For the same reason you wouldn't use it on door hinges, it should never be used for 
chair and sofa mechanisms. Because WD-40 attracts dust and turns things black, over 
time that dirt accumulation within the moving parts will build up and eventually start to                              fall off onto carpeting creating a terrible black mess that is nearly impossible to remove.
