How do you Clean a Warehouse or Industrial Building Ceiling?
This is an issue I have had a many of our properties in the past. When we acquire an older building the ceiling, joists, conduit, piping, etc is FILTHY with dust and whatnot. What kind of service or equipment is needed to clean these.? It really makes the space look so much worse than it actually is

In the past when we have had painters repaint the ceilings and they have used compressed air or blowers to knock most of the dust down to the floor and then cleaned it up, but that makes a mess. Is there a better way?
