When should you get new wiper blades?
This depends on how often you use your windscreen wipers and the different conditions your car is exposed to. Rubber deteriorates in hot, cold, wet or dry weather, so we recommend changing your wipers every 12 months, or if you experience any of the following:
- Juddering on the screen
- Noise or squeaking across both dry and wet screens
- The blade feels worn down or has notches when you run a finger down it
- Your blade leaves streaks or unwiped areas on the windscreen
How to fit wiper blades
Step One: Lift up your wiper arm from the screen
Step Two: Unclip the old wiper blade, either by sliding the blade out of the clip system or pulling it gently off the arm. Be very careful not to let the arm snap back onto the windscreen, as this could cause damage.
Step Three: Clip your new wiper blade onto the arm, taking care to ensure there's a firm 'clicking' noise or feeling. Give it a wiggle to make sure it's secure.
Step Four: Replace the arm and blade slowly onto the windscreen. If it doesn't look straight, or the whole blade doesn't sit on the glass, then it hasn't been fitted correctly.
Repeat the process for the other three (or more) wiper blades on your car.
