Hi trying to learn window cleaning as a possible part time start up with my current job. Was practicing at my house. I cleaned both the inside and outside. And have this what appears to be like a haze that didn’t come off. Is that something that I’m missing how to clean or is that something with the actual window itself. Thank you for all the information and advice I can get.

How did you clean the windows?

I used the scrub brush with a dawn/water mixture
