Bloxygen vs. ?

[Mark J]

Anyone ever try using computer duster spray as a substitute for Bloxygen?  My can says its difluoroethane.  Don't know if that's inert, but it's not oxygen.

Interesting timing on your question Mark. Not duster spray, but I recently tried using freeze spray with with a half empty can of Tung Oil. The stuff is typically used to rapidly chill electronic parts during diagnostic procedures. Anyway, I gave it a good shot & closed the lid tightly. A couple of days later, the can was squished almost flat, like a vacuum pump has been hooked up to it. The gas had almost entirely dissolved into the liquid; when I shake the can there is hardly any splashing sound.  Very interesting, but I hope it hasn't ruined the tung oil.

I surprised they still sell it to release into the atmosphere.

Looks like it's not as bad as some:     https://en.wikipedia.org/wiki/1,1-Difluoroethane

There is hardly anything that dissipates oxygen more than CO2. Having access, that’s what I use.

That's interesting, would have thought the freeze spray would have expanded as it warmned.  Hope you can get the can open again.

When held upright, the can sprays liquid, so I held it upside down to just spray the gas. It comes out at close to room temperature. Expansion would have been minimal. A chemist would be able to explain it better I'm sure, but I just assume that the gas has a very strong attraction to the liquids in the tung oil. I have no idea if this is the same stuff that is used in the canned air.
