Streaking Wipers: Why They Happen and How to Fix Them

When your streaking wipers, a common car issue where windshield wipers leave smears or lines instead of clearing water cleanly. Also known as wiper streaking, it’s not just annoying—it’s dangerous. If you can’t see clearly in rain, fog, or snow, you’re driving blind. And it’s not always the wipers’ fault.

Most people blame the wiper blades, and yes, worn rubber is the #1 cause. But streaking can also come from dirty windshields, old or dirty wiper fluid, the liquid sprayed onto the windshield to help wipers clean effectively. Often called windshield washer fluid, it needs to be clean and matched to your climate, or even oily residue from pollution or tree sap. A quick wipe with vinegar or rubbing alcohol can fix a dirty glass. But if the blades are cracked, hardened, or bent, no amount of cleaner will help. You need new ones.

wiper blades, the rubber strips attached to the wiper arm that make contact with the windshield. Also known as windshield wiper blades, they’re designed to last 6 to 12 months—but heat, sun, and cold wear them out faster than you think. If you hear squeaking, see gaps in the wipe, or notice the rubber peeling, it’s time to replace them. Don’t wait until you’re stuck on the motorway in a downpour. Most replacements take under 10 minutes and cost less than £20.

Some drivers think upgrading to premium blades helps—but the real difference is in fit and material. Silicone blades last longer and resist freezing better than standard rubber. Beam blades hold their shape better on curved windshields. But the best blade is the one that fits your car and matches your driving conditions. Check your owner’s manual. Or bring your car in—we’ll match the right size and type for your make and model.

And don’t forget the wiper arms. If they’re bent or losing tension, they won’t press the blade flat against the glass. That causes uneven wiping and streaks. A quick check is easy: lift the arm and let it drop. If it bounces or doesn’t sit snugly, it needs adjusting or replacing. Most garages fix this in minutes.

Streaking wipers are a symptom, not the problem. Fixing them means checking the whole system: blades, fluid, glass, and arms. You don’t need fancy tools. Just a clean cloth, some vinegar, and the right replacement parts. And if you’re not sure what’s wrong, bring your car in. We’ll test the wipers, clean the glass, and show you exactly what needs replacing—no upsells, no guesswork.
