Save the WD-40 for your squeaking door hinges.

Ah-yep! I've seen an air conditioner fan motor (biggie, 240AC, 2HP job) go up in flames after an all-too-inexperienced public works guy sprayed WD-40 in the lube holes in an attempt to stop a squeak. It got the base fire department to our building real quick.

(We later found it was the squirrel cage blower scraping that caused the squeak.)

I've got a buddy that works as a chemist for one of the local water works - he loves running WD-40 on their spectrometer and seeing that it is remarkably like kerosene/diesel fuel.

As an aside, WD-40 works great in cleaning grease pencil marks off of items I buy at the local thrift stores.

Cheers,
