How to Clean Bathroom Floor Tile Grout

No matter how clean you keep your bathroom, the tile grout is an area that can begin to look dirty. Once it does, it can be almost impossible to clean. You mop and mop, but it still looks discolored. Cleaning grout is not that difficult provided you are willing to use a little elbow grease and experiment until you find the right cleaner.

Things You'll Need

  • Grout brush or plastic stiff scrub brush
  • Mop
  • Bucket
  • Rubber gloves
  • Rag
  • Eye protection (optional)

Instructions

  1. How to Clean Tile Grout

    • 1

      Clear the area by removing any rugs and other items that are on the floor.

    • 2

      Sweep and mop the entire floor.

    • 3

      Ventilate the room as much as you can by keeping the door open and opening windows.

    • 4

      Depending on the cleaners you are using, you will probably want to wear gloves and eye protection.

    • 5

      Test the cleaner on a small area of grout that is not generally visible before using on your floor to ensure that it will not discolor your grout.

    • 6

      Start in the farthest corner of your bathroom floor. Apply the cleaner to a small section of floor allow to set. See Section 2 for different types of cleaners and setting times.

      Scrub the tile grout with the scrub brush using a small circular motion. It is best to use a brush specifically for tile versus an old toothbrush, which is too soft. Do not use metal brushes because you could damage the grout or the tile.

      Wipe away the cleanser with a rag.

    • 9

      Rinse the floor by mopping with clean water.
