I’ve been using bloxygen to preserve my finishes for some time, especially Waterlox which badly crusts unless you bloxygen it or squeeze out all air. When my can ran out, I researched it and found a few mentions of using compressed gas duster cans as a replacement. So I bought some cans of Dust-Off from Amazon and tried using them. For about a month now I’ve been spraying the Dust-Off into my finishes instead of bloxygen, and even the Waterlox stays perfectly liquid and usable. Doing some research, I compared the normalized vapor density of gasses involved:
Normal Air: 1 [normalized scale]
So the gas duster’s spray is much denser/heavier than even the bloxygen, making it really effective at displacing all oxygen in a finish can. I’ve heard that argon is less reactive than other substances, but after trying the gas duster in waterlox, wipe-on poly, danish oil, and spar urethane, I can report that it works perfectly with no skinning or change in quality of the finish. So for oil finishes, the gas duster is a perfect bloxygen replacement. I can get the gas duster cans for $5-$6 each online, as opposed to $13 for the bloxygen, and they seem to last much longer (maybe several times longer). I also use them for removing dust before finishing, so win-win.
I have not tried this with any water-based, lacquer-based, or alcohol-based finishes… I’d be curious to hear other people’s experiences and results.
