While it might seem like a daunting task, removing grout stains from your tile is not as difficult as it may appear.

Total Time: 6 minutes

1. Identify the Type of Grout and Stain

The first step in removing grout stains is to identify the type of grout and stain you’re dealing with. There are different types of grout, including cement-based grout, epoxy grout, and furan grout. The type of grout may determine the best way to clean it.

2. Gather Your Cleaning Supplies

You will need a few basic cleaning supplies to remove grout stains. These include a scrub brush or an old toothbrush, a spray bottle, a sponge, and your chosen cleaner.

3. Choose Your Cleaner

There are many commercial grout cleaners available, but you can also make your own at home. A popular homemade solution is a mixture of baking soda and vinegar. This solution is non-toxic and can effectively remove many types of stains. However, it’s important to note that vinegar is acidic and may not be suitable for all types of tiles, such as marble or limestone.

4. Apply the Cleaner

Apply your chosen cleaner to the stained grout. If you’re using a homemade solution (see how to make them below), apply a baking soda paste to the grout lines, then spray with vinegar. Let the solution sit for a few minutes to break down the stain.

5. Scrub the Stain

Use your scrub brush or old toothbrush to scrub the grout. Be sure to scrub thoroughly to remove the stain.

6. Rinse and Dry

After scrubbing, rinse the area with clean water. It’s important to remove all the cleaning solution to prevent residue. After rinsing, dry the area thoroughly to prevent water spots and further staining.

Preventing Future Grout Stains

Prevention is key when it comes to grout stains. Regularly cleaning your tiles and grout can help prevent stains. Additionally, sealing your grout can provide a protective barrier that prevents stains.

The Science Behind Grout Stains

Understanding the science behind grout stains can help you tackle them more effectively. As mentioned earlier, grout is porous, meaning it has tiny holes that can absorb liquids and dirt. This is why grout can easily become stained, especially in areas like the bathroom or kitchen where it’s exposed to a lot of moisture and dirt.

When a liquid comes into contact with the grout, it can seep into these pores. If the liquid contains coloring agents, like coffee or wine, it can leave a stain. Similarly, if the liquid contains organic material, like food particles or body oils, it can provide a breeding ground for mold and mildew, leading to black or green stains.

Homemade Grout Cleaners

While commercial grout cleaners can be effective, they can also be harsh and potentially damaging to certain types of tiles. If you prefer a more natural approach, there are several homemade cleaners you can use:

Hydrogen peroxide is a natural bleaching agent that can help remove stains from white grout. In our testing you want one with a higher percentage count so make sure it’s the correct one for cleaning. Mix it with baking soda to make a paste, apply to the grout, let it sit, then scrub and rinse. Make sure when you handle Hydrogen Peroxide that you’re using gloves as it can irritate the skin.

Alternatively, you could use something such as Lysol if you’re worried about mixing chemicals.

Lemon Juice

Lemon juice is acidic and can help break down grout stains. You can also mix it with Vinegar to make a powerful stain remover. However, like vinegar, it should be used with caution on certain types of tiles. Make sure this is pure lemon juice and doesn’t contain any sugars.

Remember to always test a small, inconspicuous area first when using a new cleaner.

Understanding Grout and Its Stains

Grout is a type of cement used to fill the gaps between tiles. It’s porous, meaning it can absorb liquids and dirt, leading to stains over time. The most common types of grout stains are caused by mold and mildew, especially in damp areas like the bathroom or kitchen. Other types of stains can be caused by spilled food, drinks, or household chemicals.

The Importance of Grout Sealing

One of the best ways to prevent grout stains is to seal your grout. Grout sealer is a product that you apply to the grout lines after they’ve been cleaned. The sealer fills in the pores of the grout, creating a protective barrier that prevents liquids and dirt from being absorbed.

There are different types of grout sealer, including penetrating sealers and membrane-forming sealers. Penetrating sealers seep into the grout and provide protection from within, while membrane-forming sealers create a non-porous layer on the surface of the grout.

Grout should be sealed after installation and then resealed every one to two years, depending on the amount of traffic the area receives and the type of sealer used.


Removing grout stains from tile can be a simple process with the right tools and techniques. Whether you choose a commercial cleaner or a homemade solution, the key is to scrub thoroughly and rinse well. With regular cleaning and preventative measures, you can keep your tiles looking their best.
