CAS 8052-41-3 shows as Stoddard solvent, 64742-89-7 is called naphtha. Not sure the exact difference or if it is meaningful.

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?
