Hey fellow window cleaners, I have a chain of coffee shops that we clean on a bi-weekly basis. Out of their 14 locations, there are 2 that have an issue with the inside windows fogging up. It’s almost a mix of fog and some sort of film, because when you mop and squeegee it, the water is a whitish tint.
I wanted to see if any of you are seeing this. If so, is there a good product that we can use to prevent this? I think we can up sell the service/product because the facility manager has mentioned it as well.
