What are the three formulas for automotive windshield washer fluid?
2 Answers
Three formulas for automotive windshield washer fluid are introduced as follows: The first formula: 5% propylene glycol methyl ether, 14% ethylene glycol, 80% isopropyl alcohol, 1% nonylphenol (EO) 9-10 ether. Dilute with purified water at a ratio of 1:1 when in use, suitable for winter use. The second formula: 12% propylene glycol methyl ether, 76% isopropyl alcohol, 12% propylene glycol. Mix with purified water at a ratio of 1:1 for winter use. For summer use, dilute it 5 times further. The third formula: 6.0% dipropylene glycol methyl ether, 1.0% nonylphenol (EO) 9-10 ether, 16.0% propylene glycol methyl ether, 10.0% isopropyl alcohol. Dilute with purified water at a ratio of 1:1 for summer use.
I've been driving trucks long-distance for over a decade and regularly use three DIY windshield washer fluid recipes. The first is a basic version: one cup of white vinegar mixed with one cup of water, plus a few drops of dish soap—works great for daily windshield cleaning. The second is for winter: half isopropyl alcohol (rubbing alcohol) mixed with half water, with precise measurements to prevent freezing but avoid excess to prevent rubber part corrosion. The third is for convenience: just buy pre-mixed antifreeze washer fluid from the store—it's affordable too. Extra tip: regularly spray-clean the washer nozzles to prevent clogging. Driving with poor visibility in winter is dangerous, so I check the concentration monthly to ensure safe driving.
