Apply a vinegar solution to the baking soda grout

  • Pour equal parts water and white vinegar into a squeeze bottle after preparing the mixture.
  • Spray baking soda into the vinegar solution after that. As soon as the natural cleaning process begins, you should hear a bubbling sound and observe bubbles.
  • It is not advised to use vinegar if your stone tile is natural.
  • Whenever bubbles appear, the chemical interaction between the vinegar and baking soda has already begun.
  • Typically, the response lasts a few minutes. After the bubbling stops, the chemical cleaning process begins.

Scrub grout lines with a brush

  • Use a nylon bristle scrub brush or scrub brush along the grout lines.
  • Pay attention to the corners and edges and clean those areas as well.

Mop the floor with water

Use a mop and water to remove the baking soda and vinegar residue.

Rinse your mop and change the water frequently during the cleaning process so you don’t continue to spread the residue on the floor.

  • Be sure to pour enough to cover the grout lines completely.
  • To avoid having a completely wet floor, it is necessary to clean a part of the floor.
  • For scrubbing, bleach mixture into grout lines uses a nylon bristle brush.

For optimal results, it is necessary to allow the oxygen bleach solution to settle in.

  • Pass the brush back and forth in the grout.
  • Don’t forget to scrub the corners and around the edges of the floor, as dirt and grime tend to accumulate here.
  • Dip the brush in oxygenated bleaching powder to increase the cleaning power.
  • If you find a darker or more noticeable stain, you can prepare a stronger oxygen bleach solution by dipping your wet brush directly into the oxygen bleach powder.
  • To prevent water from mixing with your main container of oxygen bleach powder, pour a small amount of powder into a separate container.

Rinse the floor with water and wipe dry

Pour clean water directly onto the tile floor and dry it with a clean towel or mop.

Bleach is a stone-safe grout cleaner, which can help you and make a lot of work easier.

Create a kind of paste

  • Mix ¼ cup hydrogen peroxide, ¾ cup baking soda, and one tablespoon liquid dishwashing soap.
  • This highly effective paste cleans grout in three ways:
  • The baking soda works like a natural abrasive to scrub the grout.
  • Sodium bicarbonate reacts chemically with hydrogen peroxide releasing bleaching oxygen ions.
  • One product that can help you loosen dirt and remove grease is dish soap. 
  • The bleaching reaction of the chemical may affect the colored grout. Test in a hidden corner of the floor before cleaning the entire floor.

Apply the paste with a nylon bristle brush

A toothbrush or nylon scrub brush works well.

Apply the paste to the grout around the edges and between all the tiles to get a uniform and clean appearance.

Allow the mixture to settle for 15 minutes.

You may see a bubbling reaction when the baking soda and hydrogen peroxide interacts. Give the paste time to work into the grout to remove stains on the marble completely.

To remove all solutions, rinse the grout with warm or hot water. 

  • To rinse the grout solution, pour a small amount of water directly onto the tile floor. 
  • Be careful as wet tile floors can be very slippery.

Use a rag to wipe off the grout and remove any remaining residue or dirt.

  • Wipe the remaining grout paste by gently rubbing the floor with a cloth.
  • This can be done by dragging the fabric on the floor with both feet.

Mop the floor with clean water

  • Ensure there is no soap or residue by thoroughly mopping the floor with a cotton mop or sponge.
  • For a clean finish, change the water frequently and rinse the mop.
  • Another simpler option is to use grout and tile cleaner.

Method 4: Cleaning grout with a steam cleaner

Rent or purchase a steam cleaner

  • Steam cleaners can effectively clean and disinfect all tile and grout types, as they contain no chemicals.
  • To find a machine for rent or sale, please visit your local store.
  • Make sure the steam cleaner you purchase has the proper accessories for cleaning grout:
  • Steam hose
  • Small brush attachment

Follow the manufacturer’s instructions for assembling and filling the steam cleaner.

To avoid causing damage to the equipment, it is necessary to read the instructions carefully.

Fill the tank with clean water up to the fill line according to the instructions in the manual.

  • Do not add soaps or chemicals to the water tank of the steam cleaner.
  • The steam cleaner’s instruction manual will tell you how long to wait after turning on the machine before cleaning.

Move the brush over the grout.

  • May start on one side of the room and move toward the other end of the room.
  • The steam will lift dirt and grime from the grout and kill any mold and mildew present.

Use a mop for scrubbing excess moisture after cleaning.

  • Steam cleanings will remove all grout sealers, so only use a steam cleaner if your grout is not sealed or if the sealer is old and you are ready to remove it.
  • For many, the solution is steam-clean marble grout. However, not everyone has these devices that make your life simpler. Products around marble are usually very good for stains.
