How to Fix New Car Wiper Blades That Don't Clean Properly?

You can rotate the entire wiper bracket 180 degrees (some brackets allow this). You can pull the wiper rubber strip out of the bracket, swap the two ends, and then reinsert it into the bracket (keeping the bracket stationary while rotating the rubber strip 180 degrees). Adjust the pressure of the wiper arm against the windshield (the tension of the swing arm spring) by simply bending the swing arm with your hand (incomplete cleaning of the windshield is also a pressure issue). Simply use pliers to twist the front end of the wiper arm slightly. If the wiper jumps when moving upward, twist it counterclockwise; if it jumps during the return stroke, twist it clockwise.
I noticed the wipers weren’t cleaning properly right after getting my new car, with raindrop streaks obstructing visibility. This is common in new cars because the windshield comes with a protective wax or oily film from the factory, and the wiper blades also have a coating that hasn’t been fully removed. Handling it yourself is quite simple: First, use household white vinegar or a dedicated glass cleaner to wipe the entire windshield, focusing on greasy areas with multiple passes. Then rinse thoroughly with clean water to avoid residue. Remove the wiper blades and gently clean the rubber strips with warm water and a soft cloth—avoid excessive force or strong acid/alkaline solvents to prevent rubber damage. When reinstalling, ensure the wiper arms are flat and aligned, applying even pressure. If the issue persists, it might be due to improper installation or defective wipers covered under warranty—just drive to the dealership for a free replacement. Regular pre-rainy-season checks are crucial to avoid accidents from poor visibility at night, and routine cleaning extends wiper lifespan.
