Abstract: A system for using a fluid to clean markings on a hard surface includes a cleaning hood operably mounted on wheels for movement across the hard surface with the cleaning hood positioned immediately above the hard surface, a set of a plurality of cleaning arms of a selected length, the cleaning arms mounted for rotation under the cleaning hood and defining a cleaning area swept by the cleaning arms, a plurality of nozzles, each nozzle mounted on one of the plurality of cleaning arms, a cleaning fluid connection carried by the hood, the cleaning fluid connection configured to fluidly connect the nozzles and cleaning arms to a cleaning fluid supply, a vacuum connection carried by the hood, the vacuum connection configured to apply vacuum from a vacuum pump to remove contaminated cleaning fluid from the hard surface to a waste fluid storage tank, and a second set of a plurality of cleaning arms of a second selected length, wherein the plurality of cleaning arms of a selected length may be replaced by the second s

Abstract: A mobile cleaning system to be used for cleaning organic liquids from a hard surface includes tanks for storing water, and for storing used, dirty water after cleanup. A water-based cleaner is sprayed onto the spill, which can be, but need not be, done in connection with the cleanup system. A high throughput vacuum system removes the hot water and the spill materials concurrently as the hot water is applied to the treated area. The vacuumed liquids are stored in an on-board tank for later disposal.

Abstract: A mobile cleaning system to be used for cleaning organic liquids from a hard surface includes tanks for storing water, and for storing used, dirty water after cleanup. A water-based cleaner is sprayed onto the spill, which can be, but need not be, done in connection with the cleanup system. The system then sprays heated fresh water under high pressure onto the spill. A high throughput vacuum system removes the hot water and the spill materials concurrently as the hot water is applied to the treated area. The vacuumed liquids are stored in an on-board tank for later disposal.
