Glass cleaner

[jockin my styLez]

Water in a spray bottle with about a tablespoon of joy dish soap and a microfiber cloth.

this is what we use to wipe down windows after we tint them at my tint shop..works fine for us

For average use Meguiars NXT Glass Cleaner works really well. Won't damage the tint either (Basically anything ammonia free won't damage tint) Though for the price you cant go wrong with this...

It's a bit stronger then the NXT I mentioned, and Stoners IG.
