Wiper judder refers to “jumping” wipers that shake/jump/judder when moving over the windscreen. The rubber from the windscreen wiper sticks to the glass surface even though the wiper arm continues to move. The rubber “jumps” over the surface instead of gliding smoothly over the glass.
Wiper marks are surface imperfections in the direction and line that windscreen wipers move. Simply put, these are marks in the glass caused by the movement of the windscreen wipers. They can affect your vision and are difficult te remove.
