You really shouldn't use the canned air becasue it blows the dust, threads and lint back INTO the machine instead of getting rid of it. Use a vacuum with a small attachment to suck the stuff out. You can use the canned air on the needle bar, on the bobbin case if it's in your hand - anything that won't force lint into the guts of the machine. And yeah, even blowing with your breath is not a good idea.
