Co2 as "Dust Off"???

[PeterDendrinos]

Without getting into great explanation why, I happen to carry about 30 LBS (13.6Kg) of liquid Co2 in my truck. (Ok, to inflate truck tires, after driving in very soft terrain.)

The question is weather or not Co2 might make an acceptable “Dust Off” replacement. I use Dust Off currently to remove crap from various mechanical parts, and lenses. Not film however. Does anyone know first hand if there is a problem with Co2? Perhaps too much moisture, too much something else that would dictate that I not use it in place of “dust off”?

SEveral years ago, when freon had just been taken off the market, you could buy CO2 'dustoff'. It worked fine, but was a bit expensive. I think the biggest commercial problem with CO2 is that it does not liquify at low temperatures. It takes a pretty heavy cylinder to contain enough of it to make it worth while. If you have it on tap, however, go for it.

It cannot be used like nitrogen to back fill bottles or such as an inert environment. It reacts with water to form a mild acid.

If you need another "excuse" for CO2, I respectfully suggest home brewing.

Well I tried Home Brewing many years ago. It didn’t pan out, and I gave up.

I am however a big lover of beer and would love to try again. What can you tell me about the process with co2?

I had several cans of CO2 from an air force surplus sale. I used it as dust off it worked fine but DONT shake the cans when in use. It was like a fire extinguisher. When I used the last can I could never find anything that used the same valve.

I purchase C02 in small cartridges for the purpose of bringing about this reaction with water all the time. Stored under pressure at a low temperature, this mild acid makes a refreshing drink just by itself or with a small amount of flavored syrup on a hot day, or it can be mixed about 1:1 with wine, or in a glass with a tablespoon of chocolate syrup and some milk. Clowns have been known to spray this acid, stored under pressure, directly into the faces of other clowns without causing serious injury.
