Kamaainas,
Be VERY careful where you spray your HIGHLY FLAMMABLE ALCOHOL
I am thinking, electrical cabling and connections.... those very hot power supplies... vent intakes on your PCs, TV, etc...
Oh, like regular bug sprays aren't flammable, too. And while isopropyl is "toxic," in the sense that you don't want to drink it, it's benign enough that you put it on your skin. That's why it's called "rubbing alcohol."
It's also a good chrome (faucets, 'fridge handles, the like) cleaner and a moderately good glass cleaner. I've been told that faucet and 'fridge handles are the germiest places in the house.
Yes, while it does require "notable" safety precautions and it's rather spectacular if you hold a lighter in the spray, I've used it around the house in spray bottles for over 20 years with no KBs.
Incidentally, many spray-bottle tops fit directly on the alcohol bottles.
