What to Do When the Car Windshield Doesn't Wipe Clean?
2 Answers
Methods to address a car windshield that doesn't wipe clean are: 1. Wet the glass with water, apply toothpaste evenly on the glass, gently scrub with a sponge, then rinse off; 2. Dilute windshield washer fluid with water, pour it into a spray bottle, spray it on the glass, and wipe clean with a soft, lint-free cloth; 3. Spray a small amount of water on the glass and wipe it back and forth with old newspapers. The classification and functions of car glass are: 1. Laminated glass: A transparent adhesive plastic film is placed between two or three layers of glass, enhancing the glass's resistance to breakage; 2. Tempered glass: Ordinary glass is quenched to form certain internal stresses. When impacted and broken, the glass splits into small pieces with blunt edges, reducing the risk of injury to passengers.
I've been driving for over 30 years and have dealt with poorly cleaning windshields many times. I usually park first to check if the wiper blades are aged or cracked - if I see edge cracks or hardening, I replace them immediately. Next, I clean stains like oil film or bug residue on the windshield using warm water and dish soap with a cloth to ensure smoothness. I also check the wiper fluid level and quality, recommending professional cleaning type with antifreeze for better rainy day performance. The wiper arm connection points easily accumulate dust - after wiping with wet wipes, adjust the angle to ensure proper glass contact. For routine maintenance, I inspect the system quarterly. Safety first - when visibility is poor, immediately slow down and pull over, never force driving.
