[GreenKeys] WD-40

[John, W9DDD]

Doug, that's a much better explanation that the one I sent to Jeffery.

It was suppose to have gone to the list, but when I do email from the 
iPad I never know where it's going if I don't pay close attention, which 
didn't happen that early in the morning.

Basically I said it's baaaad stuff to use on TTY equipment.

The primary problem with using it as a lubricant is that it is temporary.  The kerosene evaporates.  The small amount of other stuff in it may turn to gunk, but that will dissolve in light instrument oil.  What you need to do is use light instrument oil -- something that doesn't evaporate.  If the gunk issue is serious, degrease first, then re-lubricate.  That's ususally only necessary if the gunk was serious before you used WD-40; the kerosene in WD-40 dissolves gunk and lets the mix of gunk and kerosene act as a lubricant until the kerosene evaporates, and then you're back where you started, gunk.
