[Milsurplus] WD-40

[KD7JYK DM09]

"Do most of you that use WD-40 to clean switch contacts, clean off the
contacts with Isopropyl Alcohol before and after using the WD-40?"

WD-40 is a poor lubricant at best, so I don't use it for that and never use
it as a contact cleaner, because it's no more a contact cleaner than motor
oil.  I use various water and ethereal hydrocarbon based solvents, a fancy
name for carb cleaner, acetone, laquer thinner...  I guess WD_40 is really
good for what it was designed, displacing water in ignition systems, which I
have used it for, but it attracts gunk there too.

In reality, all I've used it for is making fire balls with a cigarette 
lighter, and haven't done that since the 80's.
