  • Patent number: 11963648
    Abstract: A grout cleaning attachment configured for removably attaching to a shoe enables a user to scrub a grout line with their foot. The grout cleaning attachment includes a brush that extends out and away from a toe section of the shoe so that a person using the attachment can see where the brush bristles are and locate the brush over the grout line. The grout cleaning attachment includes a cup section that slides over the front section of the shoe and a strap on the aft section that wraps around the person's shoe and ankle to secure the grout cleaning attachment to the shoe. The grout cleaning attachment is light in weight and easy to install and remove from a shoe being worn by a person. The brush is narrow in width and long in length so that most of the bristles will be used to brush over the grout line. Also, the brush can be curved upward in order to improve the brushing performance for cleaning a grout line.
