How to Drain Windshield Washer Fluid from a Car
2 Answers
There are methods to drain windshield washer fluid from a car: 1. Start the car, press the windshield washer button, and keep spraying until the fluid is completely used up; 2. Open the car's hood, locate the cap of the windshield washer fluid reservoir, open the cap, insert a hose into it, and use a syringe to suction at the other end of the hose. When the fluid starts to overflow, remove the syringe and place the hose on the ground, allowing the remaining fluid to drain out automatically. Windshield washer fluid, commonly known as car windshield cleaning fluid, is a consumable item in car maintenance. It is a specialized liquid designed to assist in cleaning the car's windshield, offering functions such as cleaning, anti-fogging, anti-static, lubrication, and corrosion prevention.
When I was replacing the windshield washer fluid at home, I found the easiest method is to first open the hood and locate the translucent plastic reservoir, usually marked with a blue or yellow cap, then gently unscrew the cap. Next, I used a hose connected to a siphon pump to slowly extract the liquid, or simply inserted a tube to let the fluid drain out—just be patient and avoid skin contact as some cleaning solutions may irritate. If the reservoir is low, slightly lifting the front of the car can help with drainage. Don’t forget to press the washer switch afterward to expel any remaining fluid and clean the nozzles. The whole process takes about 20 minutes, making it suitable for DIY enthusiasts to save money and skip the repair shop. Prepare some old towels and containers to catch spills and avoid environmental contamination. I recommend doing this during seasonal changes to prevent winter fluid freeze-ups and system blockages.
