Depending on the amount of use an area with tile gets is the best way to determine how often you should clean your tile and grout. If it is a high traffic area, like a kitchen or bathroom that is used everyday, we recommend cleaning your tile and grout every quarter. We also recommend re-sealing your grout lines in areas like showers and bathtubs to ensure that mold will not start to grow. If it’s an area with less use, you can maintain that with a yearly clean.
