Grout between tiles collects dirt and mud. Dirty grout lines are often noticeable and easily stand out, appearing as a different color than you originally intended. The longer the dirt and mud stay in the grout, the more likely it can cause permanent color differentiation and stained grout.

If you don't want to put in the time, effort, and money into making supplies and scrubbing the grout yourself, professionals can buff and perfect both your tile and grout for a brand-new look that could easily take an entire day to accomplish on your own.
