Review: Perfect way to refresh the color of old grout - If you don't have a large area this is the perfect "Tile Paint Marker" to touch up your grout. After using it, to cover my bathroom grout that had turned an unpleasant color over the years, my tiled bathroom looked like new. The only drawback using this pen is that grout can be abrasive and it will gradually wear the tip down. It did maintain it's shape enough to finish my small bathroom though. All in all a perfect way to refresh that aging discolored grout.
