So don't a little dish soap and dihydrogen monoxide.

Propane is a byproduct of making gasoline. So why not use gas. Slightly less explosive

R-11 was a great solvent, used to dip copper fittings in it before soldering them in R-22 ac systems, then after work use R-12 to cool beer ....boy am I old

Flash means a phase change from liquid to gas. No fires here.

I took a new position as a district supervisor, now I have to actually do stuff.

Uh not exactly. Propane is a byproduct fron processing field/green natural gas into transmission quality gas. It's typically recovered in the demethanizer tower (on a cryo setup, anyway) and sold off with the NGL stream known as Y-grade. In some instances the operator may set a depropanizer tower to specifically strip the propane component from the gas stream for LP sales, but not always.

Why not gas? Well you could but this wasn't an intentional test, just something I noticed while at work. Also, LP can't exist in atmosphere, it flashes (boils) away because atmospheric. conditions on earth say so. Liquid gasoline does exist on earth. The beauty of the LP is that the hydrocarbon will cut the grease/oil and carry it away from the tool and then completely evaporate, kinda like brake cleaner.

I'm pretty sure the bug and tar remover that you can buy at the local auto parts store essentially uses kerosene byproducts as its primary ingredient. My brother used to clean asphalt tar off the lower fenders of his car with diesel fuel. Generally it is not strong enough to harm paint, but it will strip off any wax that you had on there.

We should ban that dihydrogen monoxide stuff. Causes rusting and great damage. People die from it. Needs to go.
