How to Clean Tile Floor Grout

Updated February 21, 2017

Tile is a popular flooring choice because it's easy to clean, looks good and is quite durable. There is one drawback to a tile floor, however--the grout. Unlike floor tile, the porous grout tends to soak up dirt and spills and ends up looking stained or discoloured. Luckily, there are several cleaning options. Lean more about how to clean tile floor grout.

Sweep or Swiffer your tiled floor for daily maintenance. Wipe up any spills immediately. Damp mop with clean water as needed.

Vacuum the floor to remove any debris, lint and hair from the tile surface. Dissolve 1 cup of oxygen bleach in 2 gallons of hot water. Wet mop with the solution and wait for your floor to dry completely.

Try a spot treatment if the stain still remains. Fold a small piece of sandpaper and gently rub it along the grout line. You can also rub the stain gently with a clean pencil eraser.

Make a thick paste of baking soda and tap water, if the stain still isn't gone. Gently scrub the grout with the baking soda paste and the toothbrush or grout brush. Use a circular motion to remove more debris. Wipe the area with clean water and dry with a soft rag.

Try a multipurpose household cleaner if the grout still looks dirty. Spray or pour the cleaner onto the grout and scrub with the toothbrush. Rinse well with clean water and dry with a rag.

Pour or squirt commercial grout cleaner onto the grout as another cleaning option. Let it sit for 5 minutes and gently scrub with the toothbrush. Rinse well with clean water and pat dry.


Use a commercial grout cleaner appropriate for your grout. Always wear latex or rubber gloves when using commercial cleansers. Make sure the area is well-ventilated when using chemicals.


Do not clean grout with steel wool or brushes with metal bristles because it can make the grout crumble. Never use chlorine bleach on coloured grout because it will discolour the grout. Don't mop with dirty water because it can stain the grout. Never mix cleansers together. Mixing chemicals can produce potentially harmful fumes.
