[DelLola]

Car windshield washer fluid needs to be diluted with water. The method of adding washer fluid is as follows: 1. Turn on the wiper switch, and the washer fluid will spray from below the windshield; 2. Continue until the spray nozzles stop spraying, then open the washer fluid filler cap and add a small amount of washer fluid; 3. Turn on the wiper switch again to clean out the remaining washer fluid; 4. When the spray nozzles stop spraying for the second time, add 4 liters of washer fluid, then securely close the washer fluid cap. The functions of car windshield washer fluid are: 1. Cleaning debris from the windshield; 2. Lowering the freezing point of the liquid; 3. Ensuring the windshield remains clear and transparent for optimal visibility; 4. Eliminating static charges on the glass surface; 5. Reducing friction between the wipers and the glass to prevent scratches.
