When to change wiper blades
Noticed streaking or smearing on your windscreen? Or perhaps you’ve heard some unusual noises such as squeaking or screeching when the wipers are on? Your wiper blades could need replacing. Find out everything you need to know about when to change wiper blades today.
How long do wiper blades last
Wiper blades life span can depend on a number of factors including how often they are used, the initial quality of the blades themselves and environmental factors such as weather. Usually, it’s recommended that wiper blades last between 6 months to 1 year.
However, regular servicing and MOT tests should identify if you need your wiper blades replacing.
How to tell if wiper blades need replacing
Although, it’s advisable to not just rely on servicing and MOTs to ensure your car is at its optimum health level. Checking your wiper blades for signs of damage could be the difference between a pass and a fail on your MOT. Here are signs to look out for that your wiper blades may need changing:
- Streaking or smearing - one of the most common symptoms of when wiper blades need replacing, streaking refers to the blade leaving a streak or smear of water on the windscreen. This can be due to blades being worn down or ill-fitting blades that may have come out of place.
- Unusual noises - windscreen wipers should usually be silent or have minimal noise when being used. However, if you hear sounds such as squeaking or screeching when the wiper blades are clearing water, this could indicate they need replacing.
- Irregular movement - often when wiper blades need changing, there can be irregular movement or skipping i.e. when the wiper blades miss parts of the windscreen when it’s raining. This leaves a wet streak of where the blade has skipped over the glass and not cleared the water.
- Ragged blades - visually inspecting the wiper blades to see if there’s any damage, or if the blades are distorted, is a good way to see if you need to change your wiper blades. Lift the arms of the wipers away from the windscreen and you can more easily assess the condition of the rubber.
- Failure to clear windscreen - whether it’s rain, snow or mud, if your windscreen wipers cannot effectively clear your windscreen, it’s likely they need to be replaced.
When to change wiper blades
