If its mirrored it reads

Ive seen it since i first bought my car and never gave it an attention thought it needs some cleaning then i saw it again.At first i thought it can be cleaned from the inside but nothing happened so i cleaned it i tried cleaning it from the outside; it seemed to be gone and when in a few it was back again. My rear window shows bigger circles what is that and is it possible to replace the windows for free !!
Try using a claybar to clean your windshield. Some factory and road films can be pretty stubborn, but a rub with a claybar using a 10-20% mild detergent solution (dish detergent will do the trick) as a lubricant can remove them once and for all.
yes try clay.
if doesn't work, try a bit alcohol or maybe vinegar. otherwise you might need to use some windows polish. i had some marks on my windows before, i ended up having to polish the windows a bit to get them out

That's the result of a grease pencil that they use to identify the car along the manufacturing process. Normally it goes away after you've been through enough rainy days and the wipers have removed the residue.
However, I guess in your case 1 or 2 rainy days a year isn't going to do it!
When you apply cleaners (alcohol, vinegar, ammonia, bleach), place a soaked paper towel on the spot and then cover that with clear plastic wrap (e.g. Saran Wrap) over it to keep the area moist with the cleaner. That should speed up the process.

That dust did not go away i used everything, i tried cleaning from inside and outside but nothing happened. Today i moved my hands on the front window the place where it has 6156 is engraved its unremovable and the window is not smooth nor straight. So what do you suggest ? My friends told me that its better not to get the front window replaced because no matter what they do it wont be as perfect as it was before. Im thinking of replacing the car!!
Hmm, I agree it is very aggravating but replacing the whole car is pretty extreme, a last resort. Some CL members have had windshields replaced, for instance for cracks or rock hits, if the dealer does a good job it might be very close if not indistinguishable from the original, hopefully.

Well if i was in the US i would replace the front window but since im in Dubai i dont think its a good decision. Theyll screw the car buddy. Im going for the hard way. Tommorow morning im going back to the dealer; its either replacing the car or leave it as it is because even the rear window looks the same but it has like bubbles. Im going to be satisfied if they replace the car it would be another version hoping the "Wind Noise" is fixed & the "Glove Box" repair is done. Ill also held them responsible and try to re-install V-kool again for free, since i paid for it the first time.
Dreams may come true LOL.

I can't believe that you can't remove that grease pencil residue. I mean I do believe you, I just can't get over that it is so stubborn.
OK, here's another thing to try. Go to an automotive supply store, or a motorcycle dealer, and buy a bottle of "scratch & swirl" remover. Harley Davidson makes an excellent one, but I don't know if you have a dealer where you are. Follow the intstructions on the bottle as if you were removing a scratch from your fender.
One last thing to try. Here in the US there are places that specialize in repairing slightly cracked or chipped windsheilds so that they don't have to be replaced. If you have a place like that, try taking it to them and see what they can do.
Good luck!

Thanx for your advise
Man thats not a grease pencil residue. The window is carved with the number "6516" and
when you move your hands on that area "6516" you feel the window is not smooth and when
the car is washed and water is spilled on the front window and on that area specifically
the number shows up. Wheras if i move my hand on any part of the window other than
that area its smooth and equal.

It sounds from your latter description like the marker used on your vehicle may have caused a chemical reaction between it, and the glass itself (probably aggravated by exposure to sunlight and/or its heat). My guess anyway... While glass is a very hard substance, it does have its limitations. Replacement is the best solution, short of a new car.
