Dust, spots, glass etching, and oil film on the windshield can all cause the front windshield to become unclear. Dust on the front windshield: Since cars are often driven outdoors and parked in open-air parking lots, it is common for dust to accumulate on the windshield. In this case, the owner can simply clean the front windshield themselves. First, wipe the surface with a towel, then use glass cleaner to thoroughly clean the windshield. Spots on the front windshield: When driving in the rain, dust or impurities mixed in the rainwater can leave spots on the windshield. Regular cleaning can restore clarity. Wipe the surface with a towel first, then use glass cleaner or toothpaste to clean it—this method is relatively simple. Glass etching on the windshield: If glass etching is found on the front windshield, first wet a towel, then wipe the affected area with the damp towel, apply alcohol, and finally wipe the glass again to remove the etching. Alternatively, ammonia water can be added to water to clean off the glass etching. Oil film on the front windshield: If you drive too close to the vehicle in front, black exhaust fumes from its tailpipe can easily adhere to the windshield, forming an oil film. This oil film can blur the windshield and, in severe cases, obstruct visibility. Before cleaning, remove any sand particles to avoid scratching the glass, then use a degreasing cleaner to remove the oil film.
