How on earth do you clean the inside of the windshield without streaks? I have been using windex no streak and no matter how many times I have done it, the window is streaked. Am I using the wrong cleaner (windex), applicator (paper towels) or is there a special technique to getting this badboy clean?

Use news paper.

Don't do it in the sunlight.

I use that Stoners Invisible glass cleaner. Works pretty good. I just wipe it with a cotton tile until the streaks are gone.

I use Rain-X interior glass cleaner. It leaves it streak-free. And I use a microfiber cloth to do it.

Never heard of that one before...

Newspaper with windex cleans glass like nothing else!!!

Just don't use the shiny colored ad sections, good old black and white.

Most of the time the streaks are from any interior vinyl cleaning products you use. If you overspray or just accidentally wipe it on there and then try to clean it, it doesnt dillute it all the way leaving a streak. Try to actually wash the inside with a soap and water mix to actually clean it , but then dry it quickly if you are in a hot area. Then apply a window cleaner. I like the Stoner's glass cleaner. Then i use a microfiber or special glass towel. Its like a nylon towel or something, kind of like what you would use on your eyeglasses.

Use a good microfiber towel

Stoner Invisible Glass and a cheap microfiber towel.

It's obvious you've never been a cleaning lady. Newspaper is the defacto standard for cleaning the windows in a house and no reason it shouldn't work for our cars.

The French Maid outfit does not fit me that well...

Should I spray on the newspaper or directly on the window?

I spray it lightly on the window then use newspaper to wipe it off.
