Windscreen Scratches

Are you sure that's what scratched it - ie did you actually see it happen? I can't imagine the wiper blade providing enough force to scratch the glass on a one or two-time pass over the window. Maybe if there was something stuck to the bottom of the blade and it consistently wiped over the glass?

Cheers,

Magically appeared one day - obviously a piece of sand or a very small piece of stone caught between the wiper blade and screen. It follows the arc of the wiper blade. I replaced the blades shortly after but there was nothing impeded in the old rubber.

Bugger, must be a deep scratch. Sounds like the automatic wipers should be programmed to give a squirt of water before they activate.:angel:

I can vouch for the damage that sand can do to a windscreen. I work on Fraser Island and manage a fleet of LC utes that are always less than 25-30 000kms old, and the state of the screens deteriorates incredibly rapidly from new.

I can only put this down to the sand that inevitably winds up under the wipers as these vehicles do not generally travel during the dusk/dawn period where bug strikes are more likely. And these vehicles are also rarely driven on sealed or dirt roads where rock strikes can cause damage.

There's a lot of merit to the idea of auto wipers but if I owned a vehicle with them I dare say the feature would be turned off 99% of the time.
