North Hills Main District asked us to do their first site-wide cleaning of curbs and sidewalks. This work was completed in off hours while the center was closed. Throughout the cleaning we treated inorganic staining such as rust stains and FOG stains (fats, oils, greases) often occurring in front of store and restaurant entrances. Prior to cleaning each night, we would remove chewing gum with hot water. Following completion of work each night we hand cleaned the windows to ensure that no debris or dirt was left behind by our cleaning. As this job spanned multiple days of cleaning prior to the holiday season, it was important that our technicians left no trace of work behind each night to ensure a pleasant guest experience during the day.
