Method for preparing windshield washer fluid: 1. Prepare a bottle of high-proof liquor and pour half of it into a large beverage bottle; 2. For daily use, add an appropriate amount of household dishwashing liquid. If used in winter, additionally include antifreeze; 3. Finally, add purified water and shake well. Remember not to use tap water—opt for mineral water or boiled and cooled water. Windshield washer fluid is widely used for quick stain removal and bright cleaning on various glass surfaces, including car windows, rearview mirrors, household glass, office glass, door and window glass, and decorative glass. It features comprehensive performance, simple usage, and can also be homemade. Due to different freezing points, windshield washer fluid is categorized into winter and summer types. During cold winters, it's essential to use winter-specific windshield washer fluid to avoid freezing and causing unnecessary damage to the car.
I just refilled the windshield washer fluid for my car a few days ago, and it's actually super simple. First, you need to locate that blue or white cap with the wiper symbol under the hood—it's usually a translucent plastic reservoir. In winter, remember to use antifreeze washer fluid, either -15°C or -25°C rated, and don't fill past the MAX line. If mixing your own, blend purified water with concentrated washer fluid cleaner at about a 1:100 ratio—just pour half a bottle of concentrate and top up the reservoir. I also like adding some medical alcohol to boost cleaning power, which helps remove summer bug splatters too. But never use dish soap directly—it'll corrode the nozzles and tubing over time.
