Cleaning Windows and Mirrors Without Streaks

I've been in the housecleaning business for a little over 8 years now. Always hated cleaning windows and sliding glass doors. I had tried every cleaning product you could think of. One day I ran out of products and ideas and just used water and a squeegee. WORKED! No streaks, no foggy residue. It was a miracle!

Just make sure if you do need to wipe corners, etc, that you use a Terry cloth that's not been washed with fabric softener or dried with dryer sheets. Hope this helps!
