If smearing is still a problem despite fitting new wiper blades, try cleaning the windscreen with neat screen-wash additive or methylated spirit.
Check the condition of the wiper blades; if they are cracked or show any signs of deterioration, or if the glass swept area is smeared, renew them. For maximum clarity of vision, wiper blades should be renewed annually, as a matter of course.
To remove a windscreen wiper blade, pull the arm fully away from the screen until it locks. Swivel the blade through 90°, then depress the locking clip at the base of the mounting block, and slide the blade out of the hooked end of the arm. Where applicable, don’t forget to check the tailgate wiper blade as well. The blade can be removed by swivelling the blade through 90°, then sliding the blade from the arm. Fit the new blade using a reversal of the removal procedure.
To remove the tailgate wiper blade, pull the arm away from the window until it locks. Carefully prise the blade from the arm using the fingers only until it is released. Fit the new blade using a reversal of the removal procedure.
