Best Way to Clean Grout

Grout is an essential component in the world of tiles, as it helps hold them together and fills in the gaps. However, it can be quite the challenge to keep grout clean, especially in high-traffic areas or where moisture is abundant. In this article, we’ll explore the best ways to clean grout, from simple DIY methods to commercial cleaning products, and share tips on maintaining its cleanliness to keep your tiles looking their best.

Why is cleaning grout important?

Health reasons

Dirty grout can harbor bacteria, mold, and mildew, which can trigger allergies and other health issues. Keeping grout clean and free from such contaminants helps maintain a healthy living environment.

Aesthetic reasons

Clean grout can make a significant difference in the appearance of your tiled surfaces. Dirty, discolored grout can make your tiles look old and worn, while clean grout enhances their beauty and adds a touch of elegance to your space.

Extend the life of your tiles

Regularly cleaning grout can also help extend the life of your tiles. Dirt, grime, and moisture can weaken the grout over time, causing it to crack and crumble. This can lead to loose tiles, which may need to be replaced or repaired.

Best practices for cleaning grout

Regular maintenance

Maintaining a regular cleaning schedule is key to keeping grout clean and preventing the buildup of dirt, grime, and mold. Aim to clean your grout at least once every two weeks to keep it looking fresh and extend its lifespan.

Choose the right tools and cleaning products

Selecting the appropriate tools and cleaning products can make a significant difference in the effectiveness of your grout cleaning efforts. A stiff brush, for example, can help remove stubborn dirt, while the right cleaning solution can break down stains and grime.

Test cleaning products on a small area first

Before applying a cleaning solution to your entire tiled surface, test it on a small, inconspicuous area of grout to ensure it doesn’t cause discoloration or damage. This can help you avoid costly mistakes and ensure the best results.

DIY grout cleaning methods

Warm water and a stiff brush

For light grout cleaning, warm water and a stiff brush can be effective. Simply scrub the grout lines with a brush dipped in warm water, then rinse with clean water and pat dry with a clean towel.

Vinegar solution

A solution of equal parts water and white vinegar can be an effective, natural grout cleaner. Spray the solution onto the grout lines, let it sit for a few minutes, then scrub with a stiff brush. Rinse with clean water and pat dry.

Baking soda and water paste

Make a paste with baking soda and water and apply it to the grout lines. Let the paste sit for 15-20 minutes before scrubbing with a stiff brush. Rinse with clean water and pat dry. This method works well for stubborn stains and mildew.

Hydrogen peroxide

For more persistent stains, apply hydrogen peroxide directly to the grout lines. Let it sit for a few minutes before scrubbing with a stiff brush. Rinse with clean water and pat dry. Always test hydrogen peroxide on a small area first, as it can cause discoloration in some cases.

Commercial grout cleaning products

Features to look for in a grout cleaner

When selecting a commercial grout cleaner, look for products that are specifically designed for grout cleaning, are non-toxic, and have good customer reviews. It’s also helpful to choose a product that comes with a satisfaction guarantee or warranty.

Top-rated grout cleaning products

Some popular grout cleaning products on the market include Grout-EEZ, Goo Gone Grout Cleaner, and Zep Grout Cleaner & Whitener. These products have received high marks from users for their effectiveness in removing stains and restoring the appearance of grout.

How to prevent grout from getting dirty

Sealing the grout

Applying a grout sealer can help protect your grout from stains and dirt buildup. Grout sealers create a barrier that makes it more difficult for dirt, grime, and moisture to penetrate the grout. It’s recommended to seal grout after installation and then reseal every 1-2 years, depending on the amount of traffic and moisture in the area.

Regular cleaning

As mentioned earlier, regular cleaning can help prevent grout from getting dirty. Be sure to sweep or vacuum your tiled surfaces frequently to remove dirt and debris before they have a chance to settle into the grout lines.

Addressing spills and stains immediately

When spills occur on your tiled surfaces, clean them up as soon as possible to prevent staining. Use a clean cloth or paper towel to blot the spill, then clean the area with a mild cleaner if necessary. Prompt attention to spills can help prevent stains from setting into your grout.

When to call a professional

If your grout is severely stained or damaged, or if you’ve tried multiple cleaning methods without success, it may be time to call a professional grout cleaning service. Professional grout cleaners have access to specialized tools and cleaning solutions that can effectively remove even the most stubborn stains and restore your grout to its original appearance.


Keeping grout clean is essential for maintaining the appearance and longevity of your tiled surfaces. By using the right tools and cleaning methods, staying on top of regular maintenance, and taking preventive measures, you can keep your grout looking fresh and clean. When in doubt, don’t hesitate to consult a professional for assistance in restoring your grout to its former glory.

3. How can I remove mold and mildew from grout?

Using a paste made from baking soda and water or applying hydrogen peroxide directly to the grout lines can help remove mold and mildew. Be sure to scrub the area with a stiff brush and rinse with clean water afterward.

It’s generally recommended to reseal grout every 1-2 years. However, if you notice that your grout is becoming stained or discolored more easily or if water no longer beads up on the surface, it may be time to reseal your grout.
