I recently had a local Waffle House ask if I could clean ceiling tiles while there cleaning windows once a month. The tiles are aluminum i think. The dust and dirt stick to them like crazy because of the grease that also adheres to them. Are there efficient ways to handle this cleaning task?
Look up Steve Spung from H & S Window Cleaning out of Atlanta, Ga. I know his company used (maybe still does?) to clean Waffle House ceiling for over 50 locations or something crazy like that.
