What can I use to clean the inside of a windshield that leaves no residue?

Ive found a glass cleaner that (no joking here) is by far the BEST glass cleaner I have EVER used....its called Invisible Glass & I bought it at Lowes......use it w crumpled up newspaper & HOLY COW I swear it like there is no glass!!! LIterally like the name says its like it invisible!!! Dont use it on the outside to as Ive found that when it rains it makes it look weird....but for the inside & your house windows & mirrors it is FOR SURE the best Ive found so far

The best results I ever got were with some vinegar on a shammy. wipe clean and try not to get it too wet. Then just air dry or wipe dry depending on if you have a clean, new shammy. vinegar works with most cleaning cloths tho. as long as the cloth is clean.

Use window cleaner or just plain water with newspaper crunched up. Works wonderfully!!

Follow vic's suggestion. Use newspaper wet with plain water and follow behind with dry newspaper. You will be happy you did and no expense.

Try vinegar on it!!
