Can You Add Alcohol to Windshield Washer Fluid?
2 Answers
Industrial alcohol can be added, but it is not recommended to use alcohol-based substances as windshield washer fluid. Especially when DIY-ing without proper control of the ratio, the risks are greater. Here is more information about windshield washer fluid: 1. Simply adding alcohol to windshield washer fluid does not provide antifreeze protection. The presence of alcohol and ethylene glycol in the fluid significantly lowers the freezing point, thus serving as an antifreeze and quickly dissolving frost. 2. High-quality windshield washer fluid is made from deionized water and various eco-friendly additives, offering functions such as dirt removal, antifreeze protection, anti-static properties, and corrosion resistance. 3. Some superior windshield washer fluids also feature quick snow and ice melting, anti-glare, and anti-fog properties, playing a significant role in enhancing driving safety.
I usually enjoy tinkering with little tricks while driving. One winter, afraid the windshield washer fluid would freeze, I tried adding some white liquor from home. Within days, the wiper blades became stiff and cracked, and the windshield developed scratches and small spots. A mechanic friend said the alcohol was too harsh, corroding the rubber and paint, and even pointed out a strange smell inside the car. Now I just buy dedicated antifreeze washer fluid from the supermarket—only about ten yuan a bottle—simple and safe. Don’t play with fire like I did. Cars can’t handle reckless experiments, especially in winter when they need careful maintenance.
