Have you got any really strong anti bacterial cleaner? Dettol 4 in 1 for example, and some meaty kitchen towel, like Bounty or whatever its called now.

Give that a go. Worked wonders on my glasses when i got some T Cut on them.

And dont forget to clean the blades themselves as well. :)

>Apparently nail varnish remover (or something with Acetone) may lift it.

Cellulose paint thinner is your friend here. Comes in big tins cheap rather than in little bottles priced as cosmetics too. Less painful on the jolly old wallet when it comes to sloshing it liberally onto a rag.

Also worth a try is lighter fluid (the stuff you put in Zippo lighters), that removes all sorts of crud.

In this part of the world, when you stick you car through the car wash they give you a little packet containing a tissue thingy impregnated with something that removes car wax like magic (nose says mostly alcohol with some other unidentifiable smelly bits thrown in). The idea is that since the wax function of the wash is an "all over" deal, you need something to get the wax off the screen afterwards to make the wipers work. Works a treat too. I wonder if these are available in Britain? They come in foil envelopes containing two tissues, a "wet" one and a plain one to clean up with.

This is a subject thats been bugging me for weeks also.

Every time I think Ive found the magic bullet I get back to square 1 so here are my views as follows :-

Good hard dry newspaper wipe of a slighltly damp screen - pretty good

Household amonia wipe of screen - reasonable

Acetone wipe - very good but be carefull of the paintwork as there are no second chances.

Detergents including pressure washer stuff - waste of time largely

CIF cream or similar - okayish

Jewellers rouge past - pretty good

Meths - left rainbowy smears

New windscreen - priceless !!
