How to Clean Tile Grout: The Ultimate Guide for Sparkling Floors and Walls


Tile grout can be one of the toughest areas to keep clean, especially in kitchens, bathrooms, and high-traffic areas. Over time, dirt, soap scum, and moisture cause grout lines to turn dark and grimy, making floors and walls look old and dirty.

Fortunately, with the right cleaning methods, you can restore your grout to its original brightness without too much effort. Whether you prefer natural cleaning solutions or heavy-duty commercial cleaners, this guide will walk you through the best ways to clean tile grout effectively.


Why Does Tile Grout Get So Dirty?

Porous Surface – Grout absorbs dirt, moisture, and bacteria easily.
High-Traffic Areas – Constant foot traffic grinds in dirt and grime.
Soap & Moisture Buildup – Bathrooms and kitchens are prone to soap scum and mold.
Neglected Cleaning – Without regular maintenance, grout stains become harder to remove.


Best Methods for Cleaning Tile Grout

1. Cleaning Tile Grout with Baking Soda and Vinegar (Natural & Effective)

Best for: Light to moderate stains

What You’ll Need:

  • ½ cup baking soda
  • ¼ cup white vinegar
  • Warm water
  • Toothbrush or grout brush
  • Microfiber cloth

Steps:

  1. Make a paste by mixing baking soda with a little water.
  2. Apply the paste to the grout lines and let it sit for 5-10 minutes.
  3. Spray or pour white vinegar over the baking soda paste. It will fizz and help lift stains.
  4. Scrub with a toothbrush or grout brush to remove dirt.
  5. Wipe clean with a damp cloth or rinse with warm water.

2. Using Hydrogen Peroxide for Stubborn Stains (Great for tough grime and mold)

Best for: Moderate to heavy stains

What You’ll Need:

  • ½ cup hydrogen peroxide
  • Baking soda (optional for extra scrubbing power)
  • Grout brush or old toothbrush

Steps:

  1. Apply hydrogen peroxide directly to the grout.
  2. Let it sit for 10 minutes to break down stains.
  3. Scrub with a grout brush or toothbrush.
  4. Rinse with warm water and wipe dry.

👉 Pro Tip: Mix hydrogen peroxide with baking soda to form a paste for extra scrubbing power!


3. Cleaning Grout with Bleach (For Extremely Dirty Grout) (Strong but effective – use with caution!)

Best for: Heavy stains, mold, and mildew

What You’ll Need:

  • Chlorine bleach or oxygen bleach
  • Water
  • Toothbrush or grout brush
  • Gloves & ventilation

Steps:

  1. Dilute bleach with water (1 part bleach to 3 parts water).
  2. Apply the solution to grout lines using a brush or sponge.
  3. Let it sit for 5 minutes, then scrub.
  4. Rinse thoroughly with warm water and dry.

Warning: Avoid using bleach on colored grout as it can cause discoloration.


4. Steam Cleaning for Effortless Grout Cleaning (Chemical-free and highly effective!)

Best for: Large areas and deep cleaning

What You’ll Need:

  • Steam cleaner with grout attachment
  • Water

Steps:

  1. Fill the steam cleaner with water and let it heat up.
  2. Use the grout attachment to direct steam into grout lines.
  3. Wipe away loosened dirt with a microfiber cloth.

👉 Pro Tip: Steam cleaning is a chemical-free way to clean grout and sanitize at the same time!
