How to Clean DEFAULT / HDB Cement Grout: A Comprehensive Guide

Cement grout is a common choice for filling the gaps between tiles due to its affordability and ease of application. However, it is porous and can easily absorb dirt, stains, and moisture, making regular cleaning essential.

Here’s a step-by-step guide on how to effectively clean cement grout and keep your tiled surfaces looking their best.

Tools and Materials Needed:

  • Soft-bristle brush or grout brush

  • Mild detergent or dish soap

  • Baking soda

  • White vinegar

  • Spray bottle

  • Water

  • Hydrogen peroxide (optional)

  • Commercial grout cleaner (optional)

  • Steam cleaner (optional)

  • Old toothbrush (for detailed work)

  • Towels or clean clothes

Step-by-Step Cleaning Process:

Initial Preparation:

  • Start by sweeping or vacuuming the tiled surface to remove loose dirt and debris. This prevents scratching the tiles during the cleaning process.

Basic Cleaning:

  • Mix a few drops of mild detergent or dish soap with warm water. Use a soft-bristle brush or a grout brush to scrub the grout lines gently. Rinse with clean water and dry with a towel.

  • This method is effective for regular maintenance and light cleaning.

Deep Cleaning with Baking Soda and Vinegar:

  • Make a paste by mixing baking soda with a small amount of water.

  • Apply the paste to the grout lines using an old toothbrush or your fingers.

  • Fill a spray bottle with equal parts white vinegar and water. Spray the vinegar solution onto the baking soda paste. The mixture will fizz and bubble, helping to lift dirt and stains.

  • Let it sit for 5-10 minutes. Scrub the grout lines with a soft-bristle brush, then rinse with clean water and dry the area with a towel.

Using Hydrogen Peroxide for Stubborn Stains:

  • For tougher stains, make a mixture of baking soda and hydrogen peroxide to form a paste.

  • Apply the paste to the grout lines and let it sit for about 5 minutes.

  • Scrub the grout with a brush, rinse thoroughly with water, and dry with a clean cloth.

Commercial Grout Cleaners:

  • If natural remedies don’t work, use a commercial grout cleaner specifically designed for cement grout. Follow the manufacturer's instructions carefully.

  • Ensure good ventilation when using commercial cleaners, as some can have strong fumes.

Steam Cleaning:

  • A steam cleaner can effectively clean and sanitize grout without the use of chemicals. The high-temperature steam loosens dirt and grime, making it easier to remove.

  • Follow the steam cleaner’s instructions for grout cleaning. Move the steam cleaner slowly along the grout lines for best results.

Maintenance Tips for Cement Grout:

Regular Cleaning:

  • Regularly clean the grout lines with mild detergent and water to prevent dirt buildup. Aim to do this at least once a week.

Seal the Grout:

  • Applying a grout sealer helps protect the grout from stains and moisture. Sealing should be done every 6 months to 1 year, depending on the amount of traffic and exposure to moisture. It is cost-effective and easy to do it yourself.

Replace the Grout

  • Changing the grout to non-porous will eliminate all these issues and be effective for long-term costing, however, it is best to engage a grout specialist as it takes skills and good workmanship for even and smooth lines.

Avoid Harsh Chemicals:

  • Avoid using bleach or other harsh chemicals regularly, as they can weaken the grout over time. Stick to pH-neutral cleaners whenever possible.

Maintain Proper Ventilation:

  • Ensure good ventilation in moisture-prone areas, such as bathrooms and kitchens. This helps prevent mold and mildew growth.

Immediate Spill Cleanup:

  • Clean up spills immediately to prevent staining and moisture absorption.

Regular Inspection:

  • Periodically inspect the grout for signs of cracking or damage. Repair any issues promptly to prevent further deterioration.


Cement grout, while durable, requires regular cleaning and maintenance to keep it looking its best. By following the cleaning methods and maintenance tips outlined in this guide, you can effectively clean and preserve your cement grout, ensuring your tiled surfaces remain attractive and in good condition for years to come. Regular care and attention go a long way in maintaining the beauty and functionality of your tiled areas.
