Im in love with Rain X, ive been using it for almost 2 years now, i currently use the 2 in 1, glass cleaner and Rain X stuff. But after each car wash, i get sick of scrubbing the glass on there, especially the inside of the windshield and inside of the back window because every time i wash those particular things (both inside of windshield and inside of rear window) it always leaves streaks and i mean a ton of them. I use 1 microfiber cloth to clean and a different 1 to kinda go over the glass again to make sure theres no streaks but it doesnt work. When driving around, you see streaks everywhere...Whats a good glass cleaner? and what should i use to clean the glass with? Cloths? Certain paper towels?
