I'm wondering if you're talking about cleaning the inside of chassis, along with any dirty switch contacts?
I use compressed 'air', either a pressured air hose, or spray can to clean-out and dust inside the chassis.
I don't recommend hosing down the entire insides with contact cleaner if that's what you're thinking.
The older contact cleaner sprays did a pretty good job, but since the EPA got into the act, they've outlawed
all the chemicals that work, and we're stuck with 'non-hazardous' spray contact cleaners that I've found to be
nearly useless. What took me 1/4 can to clean before, takes about 3 cans of the new stuff.
Before we get into a lot of detail, what exactly do you want to clean? Everything, or just some specific parts?
Also, the only big-time wipe-outs I've had were the tube numbers on vacuum tubes (if yours uses any), with cleaners. Some cleaners erase the markings on the glass tubes.
If you just want to spray-out the electrical contacts, the canned spray cleaners are probably fine.
(The new stuff barely works on dirt and grime, they won't hurt the contact metal surfaces)
Do you have badly tarnished/arc'ed contacts that might need a burnishing tool?
I've never heard of anybody using 'detox', whatever that is, so I'd steer clear of it unless you have proof
the stuff won't cause you problems with your set.
