Clean windows without getting stripes
I have already read many tips to get windows clean. Now I would like to reveal my secret, how to clean windows without getting stripes.
I take per 1 liter of very warm water, 1 tsp of cornstarch. Wash the windows with them, then dry dry with a dry cloth.
It is very light, inexpensive and works great. You will see, even when brushing the water rolls off. It also keeps some rain from the window.
I have also cleaned with the agent sink, tiles and sink in the bathroom. Excellent!
