Freeze spray is pretty expensive to me ($10 for 4 ounces free shipping) and not available locally and ordering from a place with shipping charges makes it more so
canned is is easier and cheaper to get
canned air when used upside down is supposed to be like freeze spray
has anyone here tried that approach?

Is so called "canned air" real compressed air or liquid propane-butane ?
Both will blow dust way, but an evaporating spray of "lighter gas" will really cool things to sub zero levels.
So which one do you have?
I have used lighter refill cans for that,with success.
Just be cautious, it´s very flammable, stay away from sparks an open flame, and work in a ventilated room.

I've never seen air in disposable cans.
Straight air, unless ultra-cooled to a liquid, has limited cooling effect. The phase-change from liquid to gas is the real-cool part.
Many of these "canned air" products have been R-134, the less-offensive "freon" refrigerant. Yes, this will freeze your fingers off.
Hmmmm: the first "canned air" on Amazon says "Contains a bitterant additive that discourages potential abusive and misusage of the product by". I thought I knew many of the huff-drugs; I have laughing gas at my elbow, but Difluoroethane?? R-152a. Ah, "Difluoroethane is an intoxicant and precipitates fatal cardiac arrhythmia." Also "extremely flammable". Yet other can-air products do not have bitterant. So It Depends.
FWIW, our new freezer is actually filled with a special grade of.... Propane! R-290. (This is very new on the small-chiller market.)

Interesting, my previous fridge sprang a leak - the inner back panel bulged alarmingly.
Didn't test for flammability.

Probably depends on cost and intended final use.
A former University pal has set up a successful and very profitable Company purifying and deodorizing propane-butane to be used as propellant where even the slightest residual smell is to be avoided, as in home parfums, deodorants, Medical sprays, instant hipped cream, etc.
Funny thing is this is some kind of distillation, only instead of "hot", liquids are processed at very low temperatures, an apparent contradiction.
Of course, boiling point is way below zero (Centigrade)

And today we have a click-bait rumor that a famous musician's death may be related to "an addiction to huffing compressed air", as well as pills.

The details get a bit gruesome. Seems he yelled at the police and his housekeeper to leave him alone, and then nobody checked on him for a day or two.
