For bonus points, the previous tenant in my house was apparently also running a 3D printer business of some sort, so there’s a fine black powder in all sorts of unimaginably impossible-to-reach places. And he did his own electrical work, making it a miracle that the house never caught fire.
IF they also had a hobby of reloading bullets, that fine black powder might be easy to clean up with just one match… of course, it will just make a bigger mess to clean up.
