I use workshop goggles that seal around my eyes and an N95 mask to trap particulates and liquid droplets. I do end up breathing a small amount of acetone vapor. I'd be more worried about Hoppes No. 9. I stopped using it back in the 1980s because it had carbon tetrachloride in it. And benzene. They claim it no longer has benzene but there are a number of unlisted proprietary ingredients. The strong scent of Hoppes covers up the odor of individual chemicals.Other than compressed CO2 or canned air, I will NOT use anything that sprays under pressure when I'm cleaning my firearms.
There is WAY too much chemical blowing around places I don't want it, or bouncing it into my face and eyes.
I do use Hoppes No. 9 Foaming Bore Cleaner.
