weird wiper streaking pattern

[Audized]

I've been experiencing this strange windshield wiper streaking pattern and am wondering what's causing the streaks. I made sure the bolt is tightly secured and the aero wiper is attached to the arm properly, but the driver side wiper still streaks. Any idea what may have caused this problem? TIA!

ive seen that before but not sure what causes it. but try taking rubbing alcohol on a rag and wiping the blade with it. may help.

i get that a lot too, i just clean the blades and it's gone for a while

I'll give that a try. Thanks, guys!

mine have done that when the blades are wearing out. it seems like they don't clean the windshield as well either even when they don't make the marks. a new set of blades did wonders. yours might be an easier fix/cleaning though.
