They look spotless when I'm done. But I get in the car the next morning to be greeted by streaks everywhere!!!

What'* the best way to get them streakless the first time?

Have you tried a specific micro fiber towel designed to clean glass?

Sounds like they aren't getting very clean. Try a different cleaner like 409 or something with amoonia

use an absorber when you whipe the water off the car. after that, go get a bath towel and dry off behid it. streak free glass no b.*. if anyone else want to try it, tell me the resilts. the bath towel has to be dry, not damp.

Inside windows...

my mom is pimp at doing my windows... not a smear at all. i buy her dinner afterwards

Inside of car windows get a haze from vinyl dashboards giving off gasses when the sun hits them. Also, if you smoke or anything, then you get that on your windows too. To avoid streaks, you need anything on your windows to be gone. To do that you need a solvent that will cut whatever is on your windows. In general, ammonia does that very well. Use windex or 409 followed by windex. And I say use crumpled newspaper (only printed with black ink) to clean them with. Seriously. Take a big sheet of newspaper, crumple it up, spray it once or twice with windex, spray some on your windows, and scrub away. Should leave your windows streak free. if it doesn't, repeat, because that means you still have gunk on the inside of your window.

Just a side note.. As far as I remember Amonia isn't good for tint

Another Tip:
Clean the outside windows with horizontal strokes and the inside with vertical strokes. Makes it easy to see which side of the glass is having problems.
