There are a few things you can do to clean dog urine from tile if it is left on the floor. The first step is to take a damp cloth and rub the urine off of the tile. If there is too much of it, you can use a vacuum cleaner to suck it up and place it in a plastic bag. The second step is to use a plunger to suction onto the top of the urine and pull until all of the liquid has been drained from the area. Finally, use a vacuum cleaner to clean any areas that were not suctioned onto by the plunger.
