The most important for a sparkling glass is not those chemicals that u put on...
The glass WILL be sparkling if it is extremely clean. The key point is to get all kinds of dusts, stains, and dirts off. As u said, you ahve those stains on the glasses, why don't u try to wash the windshield with soem stronger detergent?
"Simply Green", i'll recommend. IT's actually a household detergent.. used for countertop?? I donno. IT tells you to silute them before you use them, but no way!! just spray some of them on (2 sprays are enough for hte whole windshield) then spray a lot of water on the windshield..
then use a wet cloth and do some serious rubbing.. Rub it like crazy.. and also make sure that the windshield stays moist..
When u get tired for 2 minutes, it's probably tim to stop rubbing and stat rinsing..
jtu rinse the windshield with a host..
then use a squeegee to wipe away the water.. If you feel that the glass is not smooth when u r wiping it, redo the pervious steps..
after you wipe it with squeegee get some towel and get rid of any water remaining. or marks left by the squeegee..
This will remove any substance ontop of the glass.. and all the oil on the glass
Those windows cleaners.. windex.. newspaper.. are all useless.. as they leave oil on the glasses.. (don't forget that finger prints are also oil)
using this products may look good when it's not bright outside. but when there is sunlight shinning through the glasses.. u'll see how much oil those products leave on yr glasses.!!
Try to remove all dirts on the glass instaead of putting layers of oily chemicals onthe glasses if u want yr wnidshield to be sparkling and clean...
If you still have the problem.. do the fingerail test..
just touch the glass with yr fingernail and see hre the dirt is..
if it's noto the outside.. checkthe inside of the glasses..
even if u don't touch them.. some dirts deposite on the inside of the glasses.. I dono Y..
but u can use the same method to clean the inside ofthe glasses. jtus put some water absorbing clothes at the bottom so that u don't make a mess in yr car.. andso that u don't have any water going into any vents..
