Cleaning Methods for Ceramic Tile Floors: A Quantitative Comparison of Conventional and Fluid Extraction

摘要

Conventional methods for cleaning and sanitizing commercial grouted ceramic tile floors involve applying aqueous solutions to floors with repeated wetting and wringing cycles using mops and two- or three-compartment buckets. In contrast, in the spray-and-vac method, fresh cleaning and sanitizing solution is applied to the floor with a spray gun and subsequently extracted by vacuum into a waste container built into the machine. For removing bacterial contamination, the data shows that the spray-and-vac machine is 60 times more effective in reducing bacterial contamination than the conventional method for typical commercial floors, such as those used for aseptic processing.
