Jiff squeezy lemon works well too and smells better than vinegar! Failing that a big hammer usually gives a very clear screen and you'll never wear out the wiper blades.................. How can carbon have a footprint, it has no feet?

I have found that a product called 'NilGlass' works well. I bought mine from Makro, so not sure if it can be bought anywhere else.

This is what I use

Wurth Trade glass cleaner

Buy it at discount from the trade counter of my local double glazing place. Smells the same as Nilglass mentioned above but more effective and cheaper per litre.

Have tried lots of solutions (fnar fnar) to get smear free outside and inside. This has been the best I have found.

Just looking through the threads in Tips and Tricks, found this informative. Thanks

had this problem for ages! - think I'll try the products that glazing companies use (as mentioned above) Current - MY 2007 HSE i6 3.2 Auto, Baltic Blue
Previous - MY2005 Discovery 3 TDV6 S, Bonatti Grey
Also own - 2011 Jaguar XF S 3.0D Polaris White

Ill be trying that one, Thanks..

I have been told that the cause of this problem is the volatile plasticizers that are used in car fabrics. If this is true, you are never going to get rid of the problem, it will always come back. So frequent cleaning is the only answer. I think the evidence supports this suggestion. I use whatever window cleaning fluid my wife happens to have under the stairs, e.g. Windowlene; they all seem to work, but not to do a permanent job.

Distilled (white) vinegar works a treat but you can only seem to buy it with pickled onions floating around in it, in the UK.

Yuup White vinegar and news paper, works every time.
MudBug, most of the big supermarkets sell their own brand of white vinegar.

Notanotherhobby,
OP was about cleaning the inside of the windscreen,
I completely agree about the use of windowlene though.

I agree that a dirty windscreen, whether inside or out, is one of the most annoying things on the planet!!
In my experience the easiest way to clean the inside is to use a clean damp microfibre cloth followed by a clean dry microfibre. If only these microfibre cloths were around when I was a lad, they make cleaning the car so easy
