How To Clean Grout On Tile Floors

September 19, 2025

Tile floors are a great choice for any home. They offer durability, easy maintenance, and a sleek appearance. Unfortunately, one common frustration homeowners face is keeping grout clean. Over time, grout lines can accumulate dirt, grime, and even mold, making floors look dull and unkempt.


If you've been wondering how to clean grout on tile floors effectively, you're not alone. The good news is that your grout can look as fresh as the day it was installed with proper care and maintenance.

Understanding Why Grout Gets Dirty

Cement-based grout is a porous material, meaning it loves to absorb dirt, spills, and bacteria. In high-traffic areas like kitchens and bathrooms, grout becomes discolored due to moisture, soap scum, and everyday foot traffic.


Even if your tile floors look clean, dirty grout lines can give the entire floor an aged or worn appearance. Regular cleaning and using the right techniques to lift embedded dirt are the key to maintaining spotless grout.

Popular (But Flawed) Ways To Clean Grout

When it comes to cleaning grout, the best method depends on the amount of buildup you're dealing with. For light surface dirt, a simple mixture of warm water and mild dish soap is often enough to refresh and brighten the grout lines. If the stains are more stubborn, applying a paste made of baking soda and water can be more effective.

However, with both of these methods, without proper rinsing and drying after scrubbing, sticky residues can be left behind, attracting dirt and stains to come right back.


You can also mix baking soda with hydrogen peroxide for deeper cleaning power— but be cautious, this combination of mixing chemicals can wear away the grout and damage its integrity over time.

NOTE: While some recommend vinegar and water, this approach should be avoided. Vinegar is natural, but its acidic properties can harm your grout.

Remember that these do-it-yourself methods are helpful for light maintenance or spot cleaning, but they can be time-consuming and ineffective for larger jobs. That's why hard surface specialists like Sir Grout are here. Our proprietary tools, methods, and products ensure your grout is thoroughly cleaned and protected long-term.

The Importance of Regular Maintenance

One of the best ways to keep grout clean is to prevent excessive buildup. Regular sweeping and mopping help remove surface dirt before it settles into grout lines. Using a pH-neutral cleaner designed for tile floors can help maintain grout's natural color without causing damage.


After mopping, drying the floor with a towel or microfiber mop can prevent moisture from seeping into the grout, reducing the risk of mold and mildew. Airing out the bathroom or wiping moisture from the tiles is also important.

Sealing your grout is another excellent way to protect it from stains and dirt absorption. Using a high-quality grout sealer such as Sir Grout's ColorSeal creates a protective barrier, making it easier to clean spills before they stain. If you've ever been frustrated with constantly scrubbing grout, applying a sealer makes a noticeable difference in the long run.

When to Call in the Professionals

Sometimes, despite your best efforts, grout can become so stained that traditional cleaning methods just don't cut it. In these cases, professional grout cleaning and sealing services may be the best solution.
