Removing Film On Windows From Painters
I have my own window cleaning company and have had problems lately. When painters use their spray on protective coating to paint around windows, when removed, it leaves a greasy film. After I have cleaned the glass there is still a film when you look through the sunlight. Is it a possibility that this protective coating is actually ruining the coating of the glass, or is there a safe way to remove it without harming the glass or its coating? I have tried different solutions, scrapers, 0000 steel wool, etc. My builder, painter and my self are all baffled. I’m looking to someone who may have experienced similar problems. This is not good for my business, since everyone is looking to me for answers.
