Prepare the Area 

Start by hoovering the area to remove loose dust and dirt. This helps prevent debris from spreading as you clean the grout.

 

Create the Cleaning Mixture

Make your grout cleaner by mixing three parts baking soda with one part water to create a paste you can spread. For tougher stains, consider adding white vinegar or purchasing a store-bought grout cleaner specifically designed for tile surfaces.

Please note: Always follow the manufacturer's recommended cleaning instructions for your specific tile type. Avoid using vinegar on natural stone tiles like marble or limestone, as it can cause damage. It is also a good idea to consult the product description to determine if your tile is pre-sealed. 

 

Apply the Grout Cleaner

Apply your chosen mixture directly to the grout lines using a spray bottle, sponge, brush, or gloved finger. Leave the solution to rest for 5–15 minutes to absorb and break down any embedded dirt and stains. If you’re using a specific store-bought grout cleaner, carefully follow the manufacturer’s guidelines and adjust application times accordingly.

 

Scrub the Grout 

After letting the mixture sit, use a firm brush or an old toothbrush to scrub the grout lines in a circular motion. Be patient with high-traffic areas or places with visible discolouration. Don’t overlook edges or corner intersections where the tiles meet to ensure you achieve an even result. If the stains don’t lift easily, consider reapplying your solution and letting it rest for up to an hour before scrubbing the grout again. 

 

Final Rinse  

After scrubbing, rinse the area with warm water to wash away any remaining mixture and loosen dirt. Use a mop or clean cloth to dry the area thoroughly. If you have an extractor fan, turn it on or open your windows to ensure good ventilation for faster drying times.  

Top Tips for Tougher Stains and Preventing Buildup

For stubborn stains, apply a paste of three parts baking soda and one part hydrogen peroxide. The peroxide releases oxygen ions that help lift even the toughest grime.

  • For a more intensive clean, consider using a steam cleaner.
  • Always spot-test harsh products first to avoid damaging your tiles.
