I've tried several different ways. They look good when I'm finished only to be streaked the next morning???
Rubbing alcohol mixed with water use circular motions using coffee filters
I agree about newspapers and I also use Windex. You may wear gloves because the newspaper print will not get on the windows but will on your hands.
A window washer told me, he uses nothing but a little dawn dish soap, and a squeeze. I started doing this, and so easy, and the windows shine.
Use vinegar and water in spray bottle and then use newspaper. Cuts buildup if you put a bit of dawn soap in. Let sit for a minute or so then use paper to scrub.
