Rain-X and coffee filters work well for me. Old restaurant trick that doesn't leave any streaks or pieces of the clothe behind

Ford4Life if right. Stoner cleaner is what I use. It is easy and looks great.

Stoner is Invisible Glass like I commented earlier. Great stuff.

Zep glass cleaner from Lowes or Home Depot, clean bathroom towels. Much better than Windex and a number of others from my experience. Regular cleanings make all of them work better. M1911

Another user of Stoner here. Great on glass. I'll do two passes. First one with a heavy application of it to lift the dirt, then another pass with a clean blue shop towel and a small amount of cleaner to get it streak free.

Meguiars perfect clarity with a quality waffle weaver microfiber. Works great and is the best streak free cleaner I've used. I then treat the outer glass with autopel.

The best window cleaner (and cheapest) hands down is distilled water and 10% pure Ammonia.

Newspaper to wipe with or a quality Micro Fiber Towel to wipe/clean with and a separate one to dry with.

Amonia is bad for tinted windows, according to my tinter. I use this, a windshield microfiber towel thing from griots garage and rubber gloves. Best setup I've had so far. Newspaper never worked well for me, I'd get it to wet or to dry
