What to Do When the Car Windshield Doesn't Wipe Clean?

First, clean the windshield with clean water and dry it. Then, apply the oil film remover to a dedicated sponge and spread it evenly on the surface of the windshield. After about one minute, rinse the glass with clean water. Here is more information about why the car windshield doesn't wipe clean: 1. The issue is not with the wiper blades but rather a layer of oil film covering the windshield, which prevents the wipers from functioning effectively. 2. The oil film mainly comes from oil mist emitted by vehicles. During normal driving, oil mist from the vehicles ahead can adhere to the windshield. After prolonged exposure to high temperatures and oxidation, this oil film becomes difficult to remove. Since oil and water are immiscible, irregular water stains and a foggy surface easily form on the glass, impairing driving visibility.
Over the years of driving, I've found that unclean windshields are often due to hardened and aged wiper rubber strips, especially in hot weather when they tend to dry out and crack. I experienced this myself—replacing the wiper blades immediately improved the situation. If it's not a rubber strip issue, there might be oil film or dust buildup on the glass surface; a few wipes with a damp cloth and some glass cleaner can usually solve it. Parking in shaded areas whenever possible helps delay rubber aging. If the wipers make unusual noises during operation, check if the wiper arm is loose; a slight angle adjustment or tightening the screws can fix it. Replacing wiper blades every six months is crucial for maintaining clear driving visibility. These simple DIY methods save time and effort while enhancing driving safety.
