Smear, Streaks, Judder

Switch on wipers. The wiper blades should travel evenly and reverse smoothly. Check for cleaning efficiency.

Check for wear

Worn edges on the blade rubbers will mean that wipers cannot clear away moisture, dirt and traffic film.

Check for ageing

Tired and lifeless rubber in the wiper blades will smear the screen.

Check for Layover

Excessive layover will cause a poor wipe because the blade is not held at the correct angle to the screen.

Check for Twisting

If wiper judders, stop mid-way through stroke. With blade removed, check that arm end lies flat against screen.

Splitting

cause: Rubber is aged and worn.

Permanent Set

Rubber is aged and will no longer strope.
