I have a MK2 focus 5dr hatch '05 and find that the rear wiper doesn't sweep enough of the rear window. As a result, I find that when looking through the rear view mirror I'm actually looking through the unswept and therefore dirty part of the window at the top (furthest from the motor end of the wiper arm). Does anyone else find this annoying?

Is it possible to fit a slightly longer wiper blade so the more of the screen is swept? If so, how long was it?

Currently the blade is 14" long. Anything longer than 16" will foul on the motor end of the wiper arm. Is it possible to buy a blade that is longer at one end than the other to overcome this problem?

I bought either a 16" or an 18" from poundland of all places, fitted it, and there was enough of a gap between the blade and the motor arm, and it got almost all but a cm (from the top) of the rear window.

That wiper blade lasted me a good 6-8 months, for £1! wasnt too bad!
