there is really nothing special about cleaning windows...just spray distilled water on them,,,dont even need alcohol...wipe dry with a microfibre towl...unless the windows are really dirty...then mix with alcohol...microfibre rag is very important...dont use news paper...although it is soft and absorbant...the ink can bleed on the cloth trim around the windshield and back glass...and newspaper falls apart in yolur hand after it gets wet...there goes your freshly detailed interior....keep it simple stupid!
