The video shows a close-up of a person's hands, covered in yellow rubber gloves, using a purple toothbrush to clean a white tiled floor. The person is scrubbing a grout line with a yellow and green cleaning paste. The toothbrush is being moved back and forth over the grout line, and the paste is spreading along the line. The person's hands are steady, and the toothbrush is being used with precision. The tiles are square-shaped, and the grout lines are straight. The cleaning paste appears to be foamy and is spreading along the grout line as the toothbrush moves over it.
