By: Lisa Harper

At this time of year, we often experience unpredictable weather conditions; it can be fine and dry one minute with spring showers the next. To ensure your visibility is always clear, no matter what the conditions it is a good idea to check that your wiper blades are in good working condition. Our handy guide explains when, why and how to change your wiper blades.

Why replace wiper blades

Windscreen wipers are essential to keep your windscreen clear so that you can see the road ahead clearly. For any car to be deemed roadworthy and to pass an MOT, it must have windscreen wipers correctly fitted and in full working order.

Wiper blades are prone to wear, as the rubber gradually perishes. As a general rule wiper blades should be replaced approximately every twelve months.  However, exposure to direct sunlight and extreme cold can quicken the perishing process, so people living in particularly warm or cold climates may find that they have to change their wiper blades more frequently. 

When the rubber of the wiper blades perishes, it can result in the wiper blades smearing your windscreen leaving you with an obscured view. Incorrectly functioning windscreen wipers can result in your car to failing its MOT. Don’t chance it, wiper blades are easy to fit and relatively inexpensive, so it isn’t worth risking an unnecessarily fail.

Common signs windscreen wipers need replacing 

If your wiper blades are presenting any of the below it is probably a good idea to change them;

- Wipers leave streaks or smears across the glass

- Windscreen wipers judder as they pass over the glass

- Wipers make unusual noises when in operation (wiper blades should operate silently)

It is a good idea to get into the habit of giving wiper blades a clean every month and check the rubber for any tears in the process. Don’t forget to check the rear wiper blade too.

How to keep your new wiper blades in good condition

Now you know how to replace your windscreen wipers we thought you’d appreciate some tips on how to keep them in tip-top condition for longer. 

- Regularly wipe the wiper rubber blade using kitchen paper or a cloth dampened with either malt vinegar or neat windscreen washer fluid to help prevent smearing.

- When you wash your car, don’t neglect your wiper blades, clean them using a sponge or cloth and spongy water for a more thorough clean.

- When you return to your car after it has been raining you should make sure your wipers are switched off before starting the car. This will prevent them from dragging on the windscreen which is abrasive to the rubber.

- In freezing conditions, you should make sure that the wiper blades aren’t stuck to your windscreen before trying to switch them on. This can help to prevent causing damage to your wiper motor unit and the rubber from tearing.
