How to Clean Car Windows Effectively?

[VonRowan]

To clean car windows effectively, follow these methods: 1. Wet the glass with water, apply toothpaste evenly on the glass, gently scrub with a sponge, and then rinse off; 2. Dilute windshield washer fluid with water, pour it into a spray bottle, spray it onto 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 reasons why car windows may not be cleaned properly include: 1. The car is parked downwind from a central air conditioning cooling tower, where water droplets split by the tower fall on the glass, forming small white spots that are hard to remove; 2. Insect secretions stick to the car glass, creating an uneven surface that is difficult to scrub off.
