Wiper creates permanent mark on the screen within months?

[ben yip]

Today, when I cleaned my car, I found out the wiper has created permanent mark on my screen.. When I use my finger to touch it, the "wiping area" is more smooth.. From what it tells me, the wiper has wipped off some kind of material on the screen, so it is more smooth..

My car is only half years old of age......Is this normal, or should I go back to warranty??

Also, I found out Toyota has removed the sticker on the bottom left of the screen. That label told you the average fuel consumption.. I found it out accidentally in a cold raining weather where there are fogs on the screen.. Not sure whether you guys found that sticker mark..

PS. Hope thw modeartors of this forum does not mind I post too much!! and might be asking stupid questions

As for your window with regards to the wipers, try cleaning the area the the wipers don't touch with a clay bar (look it up if you don't know) or some form of a glass polish. Chances are you will find that the wiper has removed something from your glass, but it's nothing that came with the car. It would be surface contaminants from the environment etc. Much like how your paint can get a buildup of these contaminants and only clay can remove it, your glass is no less susceptible to this in the long run.

As for the sticker mark, try the same recommendation as above. Moisture will build up differently on this area because chemicals from the adhesive can still remain on the glass surface.
