Inspection and Replacement
Wiper Blades are a crucial vehicle safety feature. They must be in
good enough condition to clear rain, insects, dirt and snowflakes
that can all collect on the windscreen. Use our guide to Wiper Blade
inspection and replacement for safer, clearer driving vision.
Replacement advice
> How often should a Wiper Blade be replaced?
As a rule windscreen Wiper Blades should be replaced at least
once per year. In northern Europe they will usually need replacing
once in summer and once in winter as light and moisture
deteriorate the rubber blade. In southern Europe the Wiper Blade’s
lifetime is shortened by intensive sun light (UV radiation), and will
usually need annual replacement.
> Why replace?
Wiper Blades eventually deteriorate with use, producing a streaky
or uneven finish on the windscreen. To ensure a clear, safe
field of vision even in bad weather, it is important to ensure the
Wiper Blades are regularly checked and replaced as soon as
deterioration is seen.
Make it a date
As a general rule, Wiper Blades should be
changed once a year.
