[ARC5] Contact cleaner query

[DSP3]

This post is crossed with others, but.......

Gentlemen,

I use De-Oxit D5 as my standard contact cleaner.  Its getting rather 
expensive, of late, and I looked around for a suitable substitute.  
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?

Alphatic hydrocarbon-based solvent.

Contains alphatic petroleum solvent 64742-89-7, isopropol alchohol 
67-63-0 1,1 diflouroethane propellant 75-37-6.

certified for circuit breakers, electronic relays, switches, terminals, 
sensors, printed circuit boards, motor controls.

Hmmmm,   De-Oxit D5 has same alphatic hydrocarbon but spec # is 
8052-41-3, also exact same diflouroethane propellant.

Looks like the difference is the presence of isoprop alcohol in the 
Ideal product.
