1) Glass cleaner + newspapers - yes, wadded-up newsprint (B&W preferred) leaves no streaks with regular window cleaner. It comes apart pretty quick when you rub it along rubber weatherstripping, but it really works. My wife uses it on the sliding glass doors, windows, and mirros in the house, too.
2) Damp chamois - this also works, and it's probably handy if you've just washed your car, but from what I remember, it was best when used on off-gassing residues.
Speaking of off-gassing (hee-hee), if you use any interior products on the upholstery or the dash when you do your windows, such as Armor All, prepare to see streaking in about 48 hours. That stuff will evaporate to some extent and settle on the inside of your windows, most noticeably on the windshield. Whenever I use those, I wipe the surfaces down with a clean terrycloth towel after a few hours of soak time. I think this helps, but who knows. If your windows appear very clear after all your hard work but look streaky or cloudy after a day or two, this might be your main problem.
Good luck and happy detailing!
