[ARC5] Contact cleaner query

[Dennis]

I will echo what Richard said.   If purchased as the 100 percent concentrate and applied via a needle applicator one accomplishes three things:
1). Putting it only where you want it
2). Much more effective cleaning (as the spray is only 5 percent)
3). Very economical

Also, I wonder if De-Oxit is part of the audiophile and curator/purist's conspiracy for pricing?  Not being either a chemist or metallurgist, and only a smattering of corrosion control engineering, I ask anyone here if the over-the-counter industrial contact and switch cleaner Ideal #40-610 product might be an acceptable substitute product?  I got two BIG spray cans w/ nozzle (like De-Oxit) from an electrical supply house for $7 each.   Lowe's has it, too.  Most older MIL gear doesn't have exotic plastics, etc. so maybe OK for older stuff, at least?
