The answer to 'how long does grout cleaning last' is that the duration of a professional grout cleaning can vary, but typically lasts 6 months to 1 year before needing to be reapplied. The longevity of a grout cleaning depends on factors like the amount of foot traffic in the area, the type of sealant used, and proper maintenance. A high-quality grout sealer applied by a professional cleaning technician can help protect the grout and extend the time between cleanings.
Proper grout maintenance, such as regular cleaning and resealing, is important to keep it looking its best and prevent staining or deterioration over time. With proper care, a professional grout cleaning can last for several months to a year before needing to be repeated.
