As the title says, customer has had decorator do windows, rubbed down and then wiped all woodwork and some of the glass with white spirit. Cleaned this week and some windows look foggy/greasy film over them. Cleaned 3 of them twice but still not how they should be or how I would like to leave them. Using WFP and water is at 002 at moment so that's not an issue.
Question is, what's the best way to remove?
Any advice appreciated.
