I had a similar problem because I had many children and dogs in the house and a large number of windows to clean. But I was lucky to be advised to read an article from window cleaner suppliers
https://www.fortador-usa.com/blog/best- ... -suppliers. I found many interesting methods and tips from professionals that are suitable for beginners like me. I bought a compact Fortador Mini steam cleaner and a window washing kit. I also learned that it is not necessary to use chemicals during steam cleaning, which is very important because of the children and pets in the house and the fact that chemicals can be dangerous or require a lot of ventilation. The steam cleaner also effectively sanitizes all surfaces safely. Now, cleaning the house and windows in particular is a pleasure.
