Drinking Windshield Wiper Fluid: What will Happen?
Short Answer: If you accidentally drink windshield washer fluid, you may suffer from serious poisoning and blindness due to the methanol or ethylene glycol in the fluid. You should seek immediate medical attention and call Poison Control. Windshield washer fluid is a brightly-colored liquid made of methanol, a poisonous alcohol. Sometimes, small amounts of other toxic alcohols, such as ethylene glycol, are added to the mixture. Some young children may mistake the fluid for juice, which can lead to accidental poisoning. Even small amounts can cause serious damage. If you accidentally drink windshield washer fluid, you may experience symptoms such as breathing difficulty, blurred vision, low blood pressure, coma, seizures, abdominal pain, vomiting, and blindness. This is because it contains methanol or ethylene glycol, which are both toxic to the human body. Methanol can cause metabolic acidosis, a condition where the blood becomes too acidic, and damage the optic nerve, leading to permanent vision loss. Ethylene glycol can cause kidney failure, brain damage, and death. It is quite uncommon to drink windshield washer fluid due to its strong smell and taste, but it can happen if the fluid is stored in a container that resembles a beverage bottle, or if the fluid is spilled on food or drinks. You can prevent this by keeping the fluid in its original container, labeling it clearly, and storing it away from children and pets. If you or someone you know has ingested windshield washer fluid, you should seek immediate medical help. DO NOT
