Vacuum regularly to remove grit and sand. Wash your floor occasionally with Maguire's recommended floor cleaner.
Wipe up spills immediately. Do not leave any spills on the floor to dry.
Never use abrasive cleaners, soaps, paste waxes, or solvents on your vinyl floor.
Place non-staining, walk-off mats or carpet runners at every outside entry to your room. This will help keep sand and grit from being tracked on to your floor.
