Got an interesting request for cleaning windows at an in-patient psych facility. They have security bars that are not removable. The windows haven’t been cleaned in many years. I have a good working relationship with the facilities maintenance manager, and he has realistic expectations on a touch-less window cleaning.
I got to thinking, how would a fleet-washer’s brain think about tackling this sort of thing? Could it be safely two-stepped, with a pure water rinse?
