I had an old can (pre-bitterent type) of “canned air” that I used to blow out the water from atomizers after cleaning them with distilled water as part of my coil rebuilds.
I bought a replacement can from currently sold items of this type but find the bitterent that is now added to these is contaminating the atomizers and is not useable.
Does anyone have a solution to this problem? I thought of buying a small high pressure bottle of dry nitrogen and fitting it with a regulator, hose and blow gun assembly but the cost for a setup like that is pretty high.
Here is a quote from the Wikipedia page describing the problem:
Gas dusters often use a bitterant to discourage inhalant abuse, although this can cause problems for legitimate users. The bitterant not only leaves a bitter flavor in the air, but also leaves a bitter residue on objects, like screens and keyboards, that may transfer to hands and cause problems (such as when eating).
