A perfect wipe? You must be using brand new Champion wipers. One or two minor streaks in the margins of the windscreen this is acceptable.

If the wiper “misses” parts of the windscreen at high speed, replace the wiper blades and check the wiper arm for damage or wear - replace if necessary.

Deterioration of wiper blade linkage or decreased wiper pressure can leave parts of the windscreen unwashed.

Multiple and recurring streaks in the central part of the windshield are indicators the wiper is due for replacement. We recommend you change your wipers at the next opportunity.

Lack of use can result in deformation of the wiper blade lip causing a veil effect across the windscreen - particularly dangerous at night. Change your wipers as soon as possible.

Deformed wiper rubber, worn linkage or wiper arm can cause juddering across the screen leaving behind radial streaks. Change your wiper blades and replace other parts as necessary.

Noisy wipers may be a sign that the wiper element is deformed or hardened or that the wiper blade structure is worn. Time to replace them.

Wiper rubber wears out or becomes damaged with age resulting in thick bands of uncleared water left on the windscreen. Change your wipers straight away.
