I was visiting friends yesterday and noticed that the wife had covered a large ceiling vent with plastic which was affixed with sticky tape. Apparently dust would fall out of the vent onto the dining table so she took action to prevent this. The property is a rental and I fear that if the sticky tape is removed, the ceiling paint will come with it. Any suggestions on how to remove it without making it look obvious? I don't want the managing agents taking the whole bond in order to repaint the whole ceiling.
