Sufficiently pure dichloromethane is also fun stuff. It just eats through most any gloves, plastics, whatever. Even PET, and only polyethylene is somewhat resistant.

LD50 about 2mg/kg oral. By oral it's meant that well.. if you soak your hands in it it will be worse.

Still it's the goto thinner for f/ex gluing ABS. I have a couple liters sitting on the shelf right beside me.
