Symptoms
- Wipers leave streaks, smears, or a hazy film after use
- Windshield still looks dirty or blurry after wiping
- Worse in light rain or with washer fluid
- Blades may look cracked, torn, or have visible debris
Likely causes
- CommonWorn or hardened wiper blade rubberRubber degrades from sun and weather exposure over time, losing its ability to make clean contact with the glass.
- CommonDirty or contaminated blade edgeRoad grime, tree sap, or wax buildup on the blade edge causes uneven contact.
- PossibleDirty windshield surface (wax or residue buildup)A film on the glass itself, not just the blade, can cause smearing even with good blades.
- PossibleBent wiper arm or blade not sitting flushAn arm that doesn't press the blade evenly across the glass will streak in specific spots.
What to do
- Clean the wiper blade edges with a cloth and glass cleaner or rubbing alcohol to remove built-up grime.
- Clean the windshield thoroughly with a glass cleaner, since residue on the glass itself can look like a wiper problem.
- Check the blades for visible cracking, tearing, or hardened rubber, which means they need replacing.
- Replace wiper blades on a schedule (roughly every 6–12 months) rather than waiting for them to fail completely.
- Check that the wiper arm presses the blade flat and evenly across the glass; a bent arm may need gentle adjustment or replacement.
- Use a quality washer fluid rather than plain water, since some fluids include cleaning agents that help reduce streaking.
