Favorite spray for cleaning switches and potentiometers

MG Chemicals. Maybe I'd have used De-Oxit had it been available up here when I needed it, but not now.
 
DeOxit D5 spray for general switch and pot. cleaning, D100 liquid for plugs , sockets ,etc. Been using it for over ten years and it pays for itself. I also spec. it here at work for musical instrument electronics.
 
DeOxit is not expensive here, think I paid about $15 for my last can with the new straw.

I've also used CRC when I needed a zero residue cleaner.
 
Have not seen (I think) or used MG Chemicals products.
Looks like those who mentioned it are in Canada.
Are those products only available in Canada?
 
I've used both DeOxit D5 and MG Chemicals ElectroSolve for cleaning pots, and both have done a pretty good job overall. I'd probably give the edge to D5, but ElectroSolve gives me quite a bit of bang for the buck. As for the availability of MG Chemicals products outside of Canada, I buy my cans of ElectroSolve from a store right here in MA, so I'm guessing it's available in other parts of the US as well.

So this subject of contact cleaners interested me enough to see what, if any, brands were sold in stores I happened to be in. This afternoon I saw one made (in Canada) by Lloyd's Laboratories (since 1919) called Kleens-It. A 20oz spray can with straw is $7.99.

There are only two ingredients listed - tetrachloroethylene aka perchloroethylene aka PERC and carbon dioxide. The first component, I read, was described as a refrigerant and an organic solvent widely used in dry-cleaning. That sounds like it could be the successor to carbon-tetrachloride and was that not considered a desirable chemical for electrical contact cleaning? The label said it is compatible with most plastics except styrene.

I tried finding out what was in De-Oxit. It contains tetrafluoroethane (also considered a refrigerant) aka freon and mineral oil. According to Wikipedia, tetrafluoroethane is "about to be considered" as an organic solvent.

I'm obviously not a chemist but since both these products contain a similar (by intended purpose) main ingredient, would that not make De-Oxit at over $20 for a couple of ounces a bit of a rip off if the only other additive was mineral oil?

Well, I'm as cheap as they come. A can of DeOxit lasts me quite a while, and it just works.

Sure, maybe there's something out there that works just as well. MG chemicals have been around for as long as I remember, and they've always had a good rep. And if I had to pay as much for Caig products as our friends to the north, I'd probably try something else. But at $15/can for a proven performer I'm not inclined to try anything else.

BTW, a little goes a long way. A short blast is usually all it takes for all but the most tarnished pots or switches. Maybe that's why it lasts me so long.
