Looking for the best window cleaner?

For many of years I was always searching for the Perfect glass cleaner and about 7 years ago I finally found it. This stuff is great and works great with a micro towel. No streaks!  Just thought I would pass this on being I am asked all the time what I use. Give it a shot and let us know.   http://www.invisibleglass.com/Products/automotive/aerosol
