Default Whats the solution to Windscreen scratches that cause glare?

I have a friend whose old car has developed scratches on wind screen.

Reason - my guess
In appropriate cleaning procedures as car is driver driven. Often while driving in Rains when lot of mud, water and stuff comes on to the windscreen, the driver does not use water - just the wipers - causing minute scratches. I have seen this in a lot of driver-based vehicles. Its wash and wipe - not wipe and wipe!! Also windscreen seems to be cleaned with same cloth as car body - without cleaning away the dust and particles. That may have created these minute scratches.
He had also used Penzzoil solution to prevent rain water accumulation on windscreen once.

The Effect
Now even with new wiper blades the glass surface does not clean properly. There is some haze(not exactly haze but layer of water) on the screen. Also night driving creates glare from oncoming lights. At this point problem is not acute but perceptible. I think any delay will aggravate the situation.

The question
Is there anyway to change this. Make the screen clean etc. Can we polish the screen or something?

Guys please help on this one.

I dont think polishing should be done

1 way is to wash the windscreen thoroughly with colin or some glass cleaner
2 way is to replace the windscreen totally

A properly done polish does help a lot...but that is a temporary solution...replacing the wind-screen is the only viable & long-term solution. I am told by dealer technicians that the life of a wind-screen is about 4-5 years.

Aah..that is too expensive. Better to go for a change of wind screen itself, but again that would depend on what car you have

I guess what we can salvage out of the windshield depends on the extent of damage. In my case (Matiz), I went to Windshield experts and they did inspect and suggested the only solution - replace.

I got the windscreen of my six year old Indica polished. Cost me 1000 bucks and is now as good as new . Substantially cheaper than a new windscreen and you dont run the risk of a leaky seal after changing the windscreen. So I think polishing is definitely worth a try. I got mine done by the glass polish people at the Tata Motors workshop in Mumbai.

if you can get hold of cerium oxide, that is the best thing to do glass polishing.

I guess we need to get some solution this.


Can we list out preventive care we can take so that we can make windscreens last longer? I have listed a few in earlier post but if we can make a reference that will be great.

Even i would advise changing the windscreen completely. It would be safe and cause less frustation in different weathers. But be sure to get it done at a recognised workshop or else the job can come out to be really shoddy. AIS safety glass fits windscreens to cars, if i remeber correctly, so try and locate one of their repair centeres in your city.

A basic doubt- I have always wondered how wind-shield (which I presume is made using glass) gets scratched so easily?

Because I believe glass is an *extremely* hard material, and therefore necessitates special tools to cut it. Completely breaking or cracking is easy though! I hardly see any glass objects being scratched, unlike other materials like plastic or fiber (for example mobile/LCD display, fiber spectacles etc which can be scratched very easily and become hazy over time)

Even i am going through the same problem and the Genuine Windscreen of my Octavia costs around Rs. 10,000/- including Labour. I spoke to these Glass Polish guys at Mumbai and one of their Engineers is coming down to Delhi Next Week and i have requested them to inspect the Windscreen.

These Glass polish guys say that Rs. 2,500/- to Rs. 3,000/- is for Mercedes and other luxury cars.
