I've had two radios on the bench lately whose metal bat
toggle switches were nearly frozen. Discovered a good squirt
of DeOxit helps loosen things up. Set the switch with the
bat up and put some DeOxit around the round ball. It'll
soak in and work its magic. Work the bats back and forth a number
of times and the resistance will lessen. I did break two doing
this (out of 9) but I figure they were toast anyway.

I get the same results with WD40. Also, more than once, I have drilled out rivets, and disassembled and cleaned up the contacts. Reassemble using 12 or 14-GA copper wire to make "virtual rivets"

"DeOxit" pushes my buttons---do you mean D5? If so, it is intended for oxidized contacts---as often found in wafer switches. This is not the typical failure mode in a toggle switch---or the typical switch on the back of a volume control.

Agreed. My brother (who's in the repair parts business) says that half the customers that ask for DeOxit have no idea of what they want it for - all they know is they heard that "DeOxit is great for controls and switches...."

Show them Fader Lube, D5, or G5, and it's deer in the headlights.....they have an applicability chart that guides most to what they want. Caig Labs has a video that's germane....https://www.youtube.com/watch?v=otK130JVyZQ but still leaves you head scratchin'............

For me, the bloom is off the rose when it comes to CAIG and DeoxIT. Their product line is
confusing, pricey and most recently I bought some D5 in one of their flip-top cans. It is
impossible to use it without the chemical peeing-out all over the place. It's a mess. I wrote to CAIG, that of course, ignored my complaint; after all, I'm just another unimportant customer.
So I am indeed looking for a good contact cleaner.

I bought some WD40 Contact Cleaner and been using that when I don't feel like taking a bath
in DeoxIT spray.

Oh, for the good old days when you could walk into an electronics store and buy a can of
no-name contact cleaner without it being haute cuisine!

I have had at least a 95% success rate using the method you describe on toggle switches. If you press the nozzle very lightly you can get just a dribble of Deoxit to come out; use several drops. I usually actuate the toggle about a hundred times. very rapidly. Then check continuity.

I have a few pints of oleic acid, which I understand is the active ingredient in deoxit. Once I find the proper strength to mix, this will be the solution I use.

Amen. In the 70s, I worked for a regional electronics distributor and we sold a couple of cleaners - and somehow that was enough! I've studied the Caig information on which product to use where and I must be stupid, 'cause I still don't understand it!

Hey pixellany -

Can you elaborate on your process for making "virtual rivets" from copper wire? Sounds intriguing and I currently have an application for this. How do you form the ends?

Bend the wire over, and then "stake" it as if it were a rivet----but use a flat head punch. Stake gently to avoid breaking the plastic housing.
You can start by clamping the wire in a vise and forming one end with a few hammer taps

De-Oxit is fine for a first pass to clean contacts but you want a LUBE in there... BUT, WD40 does a great job on every one of these I have done. WAY cheaper, too.

Oleic acid makes an excellent flux when soldering lead strips together in a stained glass project.
