Cloudy Windows that keep on giving

[Digger11]

i am just over this. I have read everything i can about Window cleaningbut just cannot get it right.

On all 3 of my cars - the picture is a 2007 Mercedes EClass but have the same issue on all 5 past and present cars.

I clean the windows perfectly with quality glass cleaner, and then within 10 minutes cloudiness/haze/fog reappears. I wipe this off and it is crystal clear, but then return 10 minutes later and all cloudy again.

I have used all of the main window cleaners including Stoner Invisible Glass, Eclipse HD Window Cleaner, Meguiar perfect clarity, and about 5 others. I am just about to retire hurt.

I have also used many different cloths, long and shirt nap Microfibre, Drying cloths and other various Meguiar and other brand cloths made for cars.

Photo below is a bit tough to see, but at the top 1/2 of the window you can see the reappearing smudges, I can wipe them off with a brand new Microfibre cloth, but they will return, they always do.
Please help if possible.
