What is the formula for windshield washer fluid?
2 Answers
Glass water formula is as follows: 1. Materials: purified water, liquor (high-proof is best), high-quality dishwashing liquid. 2. Method: 1. Pour half a bottle of liquor into a cola bottle. 2. Add half a spoonful of dishwashing liquid. 3. Add purified water, not too full. 4. Ready to use. 3. Review: 1. At around -10 degrees Celsius, parked outdoors for 15 hours at night, it basically does not freeze. 2. When washing the glass, due to the alcohol, it evaporates quickly. After washing, the windshield is very clean, with a faint fragrance of dishwashing liquid and a light aroma of liquor. It can be used in winters when the temperature is not too low, and can be used in other seasons as well.
I've been driving for over a decade, and the windshield washer fluid recipe is actually quite simple. Making it yourself can save a lot of money and is safer. I usually use distilled water with isopropyl alcohol and a small amount of dish soap, in a ratio of roughly 90 parts water to 10 parts alcohol plus a few drops of dish soap. This mixture prevents freezing in winter and has good cleaning effects in summer. Avoid using tap water, as the mineral deposits can make the windshield hazy. When mixing your own, ensure the container is clean to avoid contaminating the nozzles. Opt for isopropyl alcohol and minimize the use of methanol, as the latter is toxic. In extremely cold conditions, you can add some ethylene glycol-based antifreeze for reliable frost protection. This method saves you from buying commercial products and reduces plastic bottle waste. One batch is usually enough for a season. Remember to drain any residual water when parking to prevent freezing and clogging the pipes. Beginners shouldn't be afraid—just follow the steps and adjust as needed. After a few tries, you'll get the hang of it.
