What to Do When the Windshield Doesn't Clean Properly?

[DiMaximus]

You can use the high-temperature steam method. Below are relevant solutions for when the windshield doesn't clean properly: Oil Film: Apply kitchen cleaner for oil stains on the glass, then use the wiper to swing back and forth while rinsing with water. Use toothpaste and a sponge to apply toothpaste on the windshield, spreading it as evenly as possible. There are professional oil film cleaners, and it's even better when paired with a water repellent! Wipe with ammonia water; just add a small amount of ammonia to water, which can make the car's glass very shiny. Oil Spots: Spots on the car can be directly cleaned with glass cleaner. If that doesn't work, toothpaste can also be used. These spots are usually rain stains.
