If your windshield wipers are on but they are still leaving behind dirt or dust, there are a few steps you can take to clean the windshield effectively:
Spray Washer Fluid: Most vehicles have a windshield washer system that sprays fluid onto the windshield to assist in cleaning. Check if your vehicle has this feature and activate it by pulling the lever or pressing the button designated for windshield washer fluid. The washer fluid will help to loosen the dirt or dust on the windshield.
Adjust Wiper Blades: Sometimes, the wiper blades may not be making proper contact with the windshield, leading to ineffective cleaning. Ensure that the wiper blades are in good condition and not worn out or damaged. If needed, you can adjust the angle or position of the wiper blades to make better contact with the windshield.
Use Windshield Wipers Intermittently: Instead of keeping the wipers continuously on, try using them intermittently. Turn them on for a few swipes, then turn them off to allow the washer fluid to soak and loosen the dirt or dust on the windshield. Repeat this process a few times until the windshield is adequately cleaned.
Manual Cleaning: If the above steps are not sufficient, you may need to manually clean the windshield. You can use a microfiber cloth or a soft sponge dampened with water or a glass cleaner. Gently wipe the windshield surface in a horizontal or vertical motion, applying light pressure to remove the dirt or dust. Be careful not to scratch the glass, especially if there are any large particles of dirt present.
Clean Wiper Blades: Sometimes, the wiper blades themselves can accumulate dirt or debris, reducing their effectiveness. You can clean the wiper blades by gently wiping them with a damp cloth or sponge. This helps remove any dirt or grime that may be hindering their performance.
Regular Maintenance: To prevent excessive dirt or dust buildup on the windshield, it's important to maintain your vehicle regularly. Keep the windshield washer fluid reservoir filled, replace worn-out wiper blades, and clean the windshield and wiper blades periodically.
If you find that the wipers are consistently unable to effectively clean the windshield, it may be time to replace the wiper blades altogether. Wiper blades typically wear out over time and lose their cleaning efficiency. Consult your vehicle's manual or seek guidance from a professional if you're unsure about replacing the wiper blades yourself.
