Try this test.

Find a squeaky door. Coat the hinges with WD-40. Squeak disappears. Check 
back in a month or two. Squeak reappears.

While WD-40 does have some lubricating properties, it's components are 
too volatile to last long. Older WD-40 cans lacked the word "lubricant" 
anywhere on the package. The packaging was changed in the last 15 or so 
years. Perhaps the regulations regarding such claims changed.

If you try the squeaky door test with a REAL silicone libricant,such as 
LPS 2, the squeak won't return for 18 months or more. 

WD-40 is good for short-term use, such as loosening corroded hardware, or 
avoiding galling of stainless steel hardware during tightening/removal. 
But don't expect it to stick around and "lubricate" for long.
