We all know the tell tale sound of a screeching wiper that's overdue a replacement – it's usually accompanied by a screen that won't clear properly, leaving smears, or un-wiped areas of glass.
But before you rush out and buy a new set (unless yours are visibly split or damaged) give them a good clean! You'll be surprised at how much dirt comes off them.
Other than that the only issue you're likely to face involves buying wipers that won't fit your car! Thankfully most 'universal' kits come with a wide variety of fixings so it's a case of choosing the fixings that most resemble the ones currently fitted.
One final thing to be mindful of is that when you've removed the blade carefully lower the arm back onto the windscreen – if you don't, and you accidentally knock it, the spring action can make it hit the screen with sufficient force to break it!
How to extend the life of your wiper blades
Wipers have a shelf life but by keeping them clean you can extend their life – Whenever you clean your car take the time to clean your windows, and the wiper blades.
Use a good quality glass cleaner and plenty of kitchen roll/paper towel to get all traces of dirt and grit from the blade.
Some people recommend applying a thin coating of silcone spray (particularly if you experience the blade screeching.
This can also extend their life as it 'conditions' the rubber, preventing it from ageing, and becoming brittle. But be aware that too much silicone can cause smearing, and leave a residue that can be difficult to remove.
How long should wiper blades last?
You should expect wipers to last for 1-2 years, but many people have blades that are considerably older, although often these are well past their best.
As soon as yours stop clearing the screen correctly (and it isn't rectified by giving them a good clean) replace them!
How much does it cost to replace wiper blades yourself?
Replacing wiper blades is one of the most simple DIY tasks you can carry out on your car, it requires no tools (usually!) and doesn't even require you to open the bonnet!
There are a wide range of prices, and it's worth noting that more expensive doesn't always mean they're necessarily better, so it's worth seeking out online reviews before deciding on a purchase.
Even blades that cost half as much are unlikely to last half as long as some high priced offerings.
