Convertible back windows - NickS
My girlfriend has a Mini Cooper Convertible, and apart from it being the most impractical car ever, she loves it to bits.

A problem she is having witht it is the back window getting filthy as soon as it rains, to the point where you actually struggle to see out, especially at night. Obviously there is no back windscreen wiper, so anyone any suggestions on how to keep it clean?

You could try some of that Rain-x stuff if it's glass. Available in any good motoring shop, Halfords for example.
