Windscreen cleaning

[liffy99]

In the few months I've had my B8 S4 I've never had a clean screen. Whatever I've tried I just couldn't seem to get rid of smearing on both inside and outside of the glass. Every time I just seem to spread a haze around, rather than removing it fully. I've been through;

2 brands of ordinary window cleaner
White vinegar and newspaper
Meths
White spirit
Engine degreaser (dabbed onto a cloth)
Proprietary foam glass cleaner
Good ol' soap and water

Nothing worked . . . . . . . until

I found a tub of leather degreaser we had used for cleaning up a sofa. It's a sort of gel that is applied to the surface and then rapidly dries to a powder whist absorbing organic grease. Took a bit of elbow grease (excuse the pun) getting it off (bit like when you leave car wax on a bit too long) but I can see clearly now !
