people were worried I was chugging denatured ethanol
Most windshield wiper fluid contains methanol, not ethanol. Methanol is much more toxic than ethanol. A few milliliters can cause permanent blindness, and a few more can be fatal.
Those are illegal to sell here. Proper alcoholics here used to drink the strongly denatured ethanol based windshield wiper fluids, but now they prefer the less strongly denatured hand sanitizers.
