Answers: its for my car
It must contain methanol. Also known as wood alcohol, methanol made a lot of people blind during prohibition when they were drinking improperly fermented underground booze. It reacts with chemicals in the brain to produce byproducts that, at high enough levels, affect your optic nerve so it no longer functions - resulting in blindness.
Does it contain methanol??
It's methanol, dear. If you drink methanol, you'll go blind.
