WINDSCREEN PROBLEMS

Facing serious challenges with my windscreen. Attached is a picture of how the windscreen looks at night when it has rained. There is a grey hazy fog-like view on some parts of the windscreen. This is NOT fog as the window has been wiped down. What is the issue? How to resolve it? Visibility is very very poor.

Hard to tell from the photo. My guess is either:

* Hardened rubber on the wiper blade rubber inserts, causing it to not wipe correctly

OR

* Moisture on the inside of the windshield. Solution is to run the Demister. Seems that Nairobi temperature is a little cooler than here, and we have to run the demister when it rains.

if its on the outside and you cant wipe it clear then it could be hard rain build up [a film of salt like deposit that builds up if the screen has been left outside for a long period of time] or if you don't know if its inside or out side it may be moisture creep if its a laminated screen,if its the build up a clean with a "CHUX bathroom magic eraser" available at supermarkets, or even a LIGHT polish with tooth paste [mix a bit of tooth paste with water to form a slurry and polish with a soft cloth] should fix it.

is it a Laminated screen? the little id info in one corner will state either "laminated or safety glass"

Hmmm, that does sound like de-laminated glass. The only solution for that is replacement.

This is a pic of a corner of the front windshield. It says NISSAN ZONELEX CENTRAL. Does that mean it is delaminated or laminated glass? What is the difference? And what is the impact on my windscreen? It has rained again today. The demister did not work on it.

1. Laminated means there are two layers of glass with a layer of plastic sheet inbetween. If cracked, it won't shatter, so it is "safety" glass.

2. The other type of safety glass is "hardened" (tempered) glass, which instead of breaking into sharp shards will shatter into tiny pieces which are not sharp.

3. The third type of glass is plain glass, which hasn't been used in autos aince before about 45 years.

De-laminated means the bond has broken down between the glass and plastic, letting moisture into the glass.

However, ZONELEX is a trademark of Central Glass for their partially-tempered glass. Typically this means the center of the glass is tempered so when your head hits it shatters. However if something hits the edges it can break into sharp pieces. Partially-tempered windscreens were used in Japan from 1970-1986 after which only laminated glass was allowed.

So it's a mystery what is wrong with it, seeing as it is not laminated glass.

as dd said it's a mystery, so try polishing it with steel wool and tooth paste, try a small area inside and out first to see if it improves, if it doesn't a new screen is needed
