I used an empty wiper fluid bottle as s drinking bottle in a party. It wasnโt the best idea since people were worried I was chugging denatured ethanol neat and getting an alcohol poisoning.

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.
