What is the method to clean the interior glass of a car?

[MacJasper]

The methods to clean the interior glass of a car are: 1. Wet the window glass with water, evenly apply toothpaste on the glass, gently scrub with a sponge, and then rinse it off; 2. Dilute glass cleaner with water and pour it into a spray bottle, spray it on the glass, and wipe it 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 glass is difficult to clean are: 1. The car is parked downwind from a central air conditioning cooling tower, and the fine particles from the cooling tower splashing on the glass form small white spots that are hard to remove; 2. The sticky secretions from insects adhere to the car glass, creating an uneven surface that is difficult to scrub off.
