A wonderful window cleaner can be made out of the following:
Mix 2 cups of hot water with 1/4 cup of vinegar and a tablespoon of cornstarch. Mix very well, and the pour into a spray bottle. Use with crumpled up newspaper. The windows will shine!
Best window cleaner ever. Take 1/2 cup of cornstarch and mix with a gallon of water. Mix very good, then you can either pour some in spray bottle or you can pour some in a container.
I have always had trouble with cleaning windows. I always get streaks. I saw in an old book to use a handful of cornstarch in a bucket of lukewarm water.
For cleaner windows the inexpensive way use 1/2 cup cornstarch to a quart of warm water.
