If anyone is having any problems getting their windows streak free and looking good, try the following. I actually learned this from my mom and it works great.

In an empty normal size spray bottle, pour about 1 inch of white vinegar into the bottle then fill the rest with water. Spray onto the windows, then whipe off with newspaper.

I know this sounds kinda wacked, but it worked for me.

I prefer using 2 microfiber towels (Costco sells a 24 pack for like $8) one's damp and one's dry. Wipe the window with the damp one, then dry with the dry one (duh?!?) and it shines them up nicely, with no sprays.

Stoner Invisible glass works best among retail items to me and is safe for tinted windows unlike the vineagr and water
