Cleaning Film Off Glass
Hi, we are a cleaning company and we have a doctors office we clean, we have never had this problem anywhere else. The glass must have some type of film on it from manufacturer, its the sliding panel glass at their front desk, No matter how we clean it, with what solution it leaves a film of swirls etc. Its awful, when the sun hits it shows all the swirls etc. Fingerprints everything seem magnified on it. Also they have frosted doors, from waiting room to back, what do we need to use on that? Their staff has also tried and was unsuccessful. They also have one panel of dark glass, same problem, shows all the swipe marks etc. Any idea what solution? We make our own of 1/2 c. amonia, 2 cups rubbing alcohol, 1 tsp dawn plus water to equal gallon. Have tried windex, and vinegar and water! Help!!!
