Grouted tiles, such as ceramic tiles, add aesthetic detail to any style of home. Ceramic tiles are grouted during installation to seal moisture out of joints and ensure durability. Although ceramic tiles only require basic maintenance, a frequent cleaning routine is crucial to a floor's appearance. Small dirt and grime particles accumulate and become caked in grout, resulting in it becoming brown and ugly. Since dirty grout mars tiles' appearance, restore its cleanliness using certain supplies.

  1. 1

    Sweep the tiles and grout joints using a broom. Clean off all loose dirt and grime particles.

  2. 2

    Pour 1/2 cup of oxygen bleach powder into a cleaning pail filled with 1 gallon of warm to hot water. Mix the powder and water using a spoon.

    Pour the oxygen bleach solution onto the grout, flooding it completely. Let the grimy grout absorb the liquid for 30 minutes.

  4. 4

    Scrub the wet grout lines with a stiff non-metal cleaning brush to extract embedded grime and stains.

  5. 5

    Refill the pail with clean water. Using a sponge mop, mop the water onto the grout joints tiles for rinsing purposes.

  6. 6

    Dry the tiles and grout joints with clean towels.

  7. 7

    Examine the grout for lingering dirt and grime. If the grout is still brown, repeat the procedure.
