I spray it on electrical contacts and other electrical components to displace water and prevent corrosion. It works great for that! I learned the trick way back when I worked as a technician in an underground missile silo.

I've always understood you are to use ED-80 on electricals, rather than WD-40.

I would be concerned that the chemicals so deposited could CREATE problems with electrical circuitry, especially when there is any contact arcing. Is the resistance of the dry material infinite? What might the voltage limits be? Maybe okay for 12 volts automotive systems, but not for 480 volt power distribution? I remember using Freon TF and Freon TMC for cleaning high voltage (20KV circuit components before potting them. Choosing the right cleaner was a real big deal.

WD-40 my be OK for a manually operate contact but not for an electrically operated contact. We had a guy try it on a bank of relays and the whole thing seized to halt! The stuff evaporates and leaves a sticky mess,not to mention where any arcing has occurred the result is pile of sticky carbon and a flash that burns the contacts beyond usable.
DO NOT USE WD-40 ON CONTACTS! keeps it use to hinges and things where you don`t mind having to reapply every 2-3months for the rest of your life.
A few mechanics have witnessed signs inside the hoods of`vehicles ``USE OF WD-40 ON THIS ENGINE WILL RESULT AND NOT PAYING THE BILL OR LITIGATION FOR DAMAGES``

Actually WD-40 worked great in old automotive distributor caps to displace condensation, 20,000-40,000 volts and plenty of arcing.

I suspect dam few to none. Having retired from the automotive industry and having been the service manager for an automobile dealership I can honestly say that I have never ever witnessed or heard of a sign, sticker, label or what ever indicating not to use WD-40 "under" the hood. We used cases of WD-40 in the shop, and under the hood.
WD-40, Water Displacement- formula # 40 is a piss poor permanent lubricant. It works great for helping to loosen rusted nuts, bolts, and frozen assemblies but the lubricating qualities are very short lived. AND of course to displace moisture. Lithium grease is a much better choice for a long term lubrication of hinges.
Sure you did. Urban legend. Something you heard from a friend of a friend.
Garbage. It does nothing of the kind.
That, of course, is the entirely *normal* result of an electrical arc
*without* WD-40.If by "a few" you mean "zero" then this is probably true.
WD40 was invented to displace water and prevent corrosion of electrical contacts. It has no to none lubricitive properties.

CALL THE SCIENTIFIC MINDS OF THE WORLD!
George can make carbon out of copper and silver contact material by passes an electrical current through them!! Many manufactures will want to hear about this atomic chemistry miracle!
Duh!

Did you even read your own link? :-)
"The long-term active ingredient is a non-volatile, viscous oil which remains on the surface, providing lubrication and protection from moisture."

Let's see what the WD-40 site says about that, shall we?
Contacts do **NOT** corrode. Contacts may tarnish being made from copper, brass, silver and gold.
Spraying it on electrical equipment to displace does not mean into the conductors. When you have water in your electrical conductors you have a bigger problem.

You missed out "Atracting dust and dirt which sticks to it causing many other problems"
Absolutely right.
/snort
... both of you are well off the "intent of use" of the product. why does THAT not surprise me :-/
I'll play. WD40 can be used to start a reluctant oil fired engine - any refined version of (oil). george
You got no fskn hope, edjut. You going to tell us aluminum does not "corrode".. /mutter
an'.. CORRODE when exposed to any number chemical compounds. Ever heard of electrolysis, dimbulb?
/mutters
Go have another run in the electrical focused newsgroups, edjut. Your well due another roundly arse kicking.
oH STFU you freaking edjut!
"water in your electrical conductors "
/mutters
Wota fskn GOOSE! george
If not corrode, they will absolutely pit. And I assure you gold contacts WILL NOT tarnish.
But do NOT use the aerosol spray to displace moisture where arcing may occur. I learnrd that the "fast" way when I used it to dry out my distributor cap, and blew it right off when I tried to start the car. (1963 Valiant slant six)
