Cleaning and Staining Grout in Tile Floors

Grout lines in tile floors can become dirty and stained over time. Clean the grout with a mixture of water, dishwashing detergent, and bleach; using a scrub brush or old toothbrush.

If the grout still won’t come clean, you might want to consider applying a grout stain to make the grout all a uniform color. Watch this video to find out more.

Further Information


Often stained grout lines can be corrected with a generous dose of bleach and some serious scrubbing with a brush. When that won’t do the trick, you may have to resort to grout stain. This material is applied directly to the grout to mask the stain and change the color and seal the grout to prevent future stains.
