Windscreen Cleaning

[ronald smith]

Hi All,
Gave the 944 a good clean up and drive over the weekend- I couldnt get the screen properly clean
I used car shampoo, glass cleaner, and finally methylated spirit- it looks a little like a dirty dishwasher
bloom you get on glasses frequently dishwashed. The screen is only about 2yrs old and about 5K miles.
Its only in lower third of screen but annoying in sunlight/ rain.
Could it be that someone has used something like Rainex but not cleaned thoroughly first.
Any ideas on cause and how can I clean it.
Any advice will be gratefully received.
Cheers
Ron

Alcohol wipes, inside and out.

Sounds odd to me, I've had old screens delaminate and go cloudy at the lower corners but it never intrudes into the viewable area. I was told by a window fitter that there was a big difference in after market screens and how long they last, so could it be faulty?

For cleaning glass I use the autogylm polish (unless the screen is badly chipped as it then shows up loads of white dots) but I second alcohol for a proper clean (but I'd imagine the meths you used would give the same results).

You could try claying - works well on glass as well as paint

Has the screen had a Rain-X or similar treatment? This produces a coating on the surface of the glass. Try a Rain-X cleaner, this is a very fine abrasive polish and will cut through most things if used enthusiastically enough.

If that doesn't work, glass companies, that cut and polish glass, might be able to provide you with an oxide powder. This is great stuff and will even take out scratches with enough attention - can maker your watch face look like new. []

It is unlikely the lamination has failed as they tend to degrade from the edges.

Believe me 30% vinegar (not the stuff you put on your fish and chips[]) in water in a spray works brilliantly.

It appears to bead but a bit of elbow grease and the beading and smearing clears so you when you get an even film across the windscreen its done. Then wip your wipers for a smooth smear free and squeek free operation.

It works well on glass, mirrors and vinyl/plastic, smells a tiny bit for a few hours but it works []

In fact it works so well I highly recommend you look up `uses for vinegar` - our household uses it constantly - cheap too.

Thanks all - for very promt replies- I think it must be something like Rainex as it looks dirty but with
an almost transparent coating- its not screen delaminating- sorry is difficult to describe the effect. I dont
think alcohol will work- on screen anyway as i gave it some welly with the meths- Drank it and breathed
on screen. Will get some Rainex remover or try clay bar as i have one of those handy.
Will let you know what works.
Cheers

In response to Hilux, I can totally agree with his solution, vinegar is the dogs left when it comes to cleaning. In my experience the best method after application is "newspaper", however I must temper that with the last time I used it (newspaper) it was prior to the new none inking variety. But it is something we used in the RAF and always worked really well. The smell as pointed out can be an issue but it does go and failing that, modern deodrants should soon shift it ...

n.b. I am not familia with the Rain-ex type products so me be "blowing in the wind" but it is a cheap and cheerful soluton.

Hi, I would also recommend Vinegar, as some chav tipped his fish and chips all over my screen and then rubbed it in. Vinegar and quite hot water removed all the grease etc, and the screen has never been cleaner.
