How to Remove Red Clay Stains From Brick

Bricks are beautiful building materials, but they can also be quite tricky to maintain. For example, if your brick home is located in an area with red clay soil, you might find that this dirt gets onto the surface of your bricks and leaves stains behind. In this blog post, we’ll tell you how to remove red clay stains from brick without having to spend too much time or money on expensive cleaners! 

How to Remove Red Clay Stains From Brick

Brick stains are one of the most common problems that brick homeowners face, and red clay stains are among the toughest because they’re so stubborn. If you want to know how to remove these stains from the bricks on your home’s exterior walls, then stick to these blog posts.

What is Red Clay?

Red clay is a type of soil that contains high levels of iron oxide, which gives it its characteristic rust color. It’s commonly found in areas with humid climates and can be quite difficult to remove from surfaces, including bricks. Red clay stains not only make your home look dirty, but they can also cause permanent discoloration if left untreated.

The good news is that there are several methods you can use to remove red clay stains from brick, and most of them involve using common household items. These methods are not only effective but also environmentally-friendly and won’t harm your bricks or the surrounding vegetation.

It’s important to note that the longer you wait to remove red clay stains, the harder it will be to get rid of them completely. So, it’s best to tackle these stains as soon as you notice them on your bricks.

Tools and Materials Needed

Before we dive into the step-by-step guide on removing red clay stains from brick, let’s gather all the necessary tools and materials:

Broom or Brush:

You’ll need a stiff-bristled broom or brush to sweep away loose dirt and debris from the brick surface. You can also use a pressure washer for this step, but be careful not to damage the bricks with too much pressure.

White Vinegar:

White vinegar is an effective natural cleaner that can help break down and dissolve red clay stains. It’s also safe to use on bricks and won’t cause any damage.

Baking Soda:

Baking soda is an all-purpose cleaner that can be used for many household cleaning tasks, including removing red clay stains from bricks. It’s non-toxic, affordable, and readily available.

Bucket or Spray Bottle:

You’ll need a container to mix your cleaning solution in. A bucket or spray bottle will work just fine.


You’ll need water to dilute the white vinegar and baking soda solution. Make sure to use warm water for better results.

Scrub Brush:

A scrub brush or a toothbrush can be used to gently scrub away the red clay stains from the brick surface.

Protective Gear:

Last but not least, make sure to wear protective gear such as gloves and goggles to protect your skin and eyes while working with the cleaning solution.

10 Effective Ways on How to Remove Red Clay Stains From Brick:

1. Use Vinegar to Remove Red Clay Stains

Vinegar is an effective solution for removing red clay stains because it can cut through them without much scrubbing. Moreover, other factors make this fluid ideal for performing this task, like its acidity and low price. The best way to go about using vinegar is to heat it first. This will be more readily absorbed by the brick, which will make the oils dissolve faster and easier. Then, mix it with water and apply it to the affected area. Alternatively, you can also use full-strength vinegar directly on the stains.

You can also use a vinegar-soaked towel or sponge to rub the stains gently. Leave it on for 10-15 minutes before rinsing off with warm water. If the stains are particularly stubborn, you can repeat this process until they disappear completely.

2. Use Lemon Juice

Alternatively, you can use lemon extract instead of vinegar which is just as effective for this purpose. The only difference is that the smell will be more pleasant but not nearly as acidic to do damage to your skin or brick components. Heat it similarly and then apply directly to the stains. The high concentration of citric acid will make it easy to break down the red clay oils without scrubbing too hard.

Use Lemon Extract

It’s important to note that lemon juice can also be mixed with vinegar for an even more potent solution. Just make sure to dilute it with water before applying it to the brick surface. But remember to always do a patch test first to ensure it won’t cause any discoloration.

3. Use Hydrogen Peroxide

Hydrogen peroxide is also a good choice for removing stains from your brick simply because many homeowners have used this chemical compound as a simple way to fight against crime. You can use it similarly to lemon extract by boiling it up first, then applying it directly to the stains, followed by scrubbing with a soft bristle brush. Rinse off once finished and let dry before using any other chemicals on your brick since hydrogen peroxide will make them less effective when in contact with it.

Hydrogen peroxide is also a good choice for removing stains from your brick simply

The good thing about hydrogen peroxide is that it doesn’t leave any residue, so you won’t need to rinse as much as with vinegar. It also won’t cause any discoloration to your bricks, making it a safe and effective option.

4. Use Ammonia

This is another influential cleaning friend that you can use to clean up red clay stains simply because it can cut through them without much effort. Its high pH level is responsible for this, so be careful when using this fluid since it can harm the brick’s protective coatings. You might want to consider wearing gloves during this process since it can be pretty caustic on the skin.

It’s best to dilute ammonia with water before using it on your brick surface. Use a soft bristle brush and gently scrub the stains, then rinse off with warm water. You can also mix ammonia with baking soda to create a paste that you can apply directly to the stains and let it sit for about 10-15 minutes before scrubbing and rinsing off.

5. Use Dish Soap

Dish soap is a standard fluid that you can use to remove stains from your brick, especially grime leftover from exterior products like car oil and brake dust. To make its cleaning properties more effective, add a cup of baking soda to the mix to use it as a scrubbing agent for dirt, which will easily be removed with your brush. Add some water to this mixture so it doesn’t dry up too quickly on the brick’s surface and become hard to remove.

The best approach is to create a paste and apply it directly on the stains, then let it sit for 10-15 minutes before scrubbing and rinsing off with warm water. You can also use this mixture as a preventive measure by brushing it over the brick surface and letting it dry before any potential staining occurs.

6. Use Saltwater

This solution might not seem ideal because it contains sodium which can also damage your brick. However, saltwater can cut through stains similar to vinegar because of its high concentration of chloride ions. This solution will be more effective when heated up like you would when making tea, so it becomes able to dissolve right into the brick instead of just sitting on top to dry in patches that are hard to scrub off.

You can also mix saltwater with baking soda to create a scrubbing paste, which you can apply directly on the stains and let sit for 10-15 minutes before rinsing off. You’ll need to rinse more thoroughly than usual as saltwater has a tendency to leave behind residue.

7. Use Boiling Water

Do you want to remove red clay stains on a brick in the most natural way possible? Then boiling water is your friend because this fluid doesn’t contain any chemicals that will make it less effective at removing grime and dirt quickly. It can be a little harsh since it can burn the skin, so be sure to wear protective clothing when handling hot liquids. However, it is an effective way of removing stains because of its ability to suck right into the pores on your brick, where you can then remove them with a brush.

Remove Them With a Brush

It’s best to use boiling water in combination with another cleaning agent, like baking soda or dish soap. The hot water will make these substances more effective and easier to remove from the brick surface. The best approach is to use a spray bottle and coat the stains with boiling water, then scrub and rinse off. Repeat this process until you are satisfied with the results.

8. Apply Red Clay Stain Remover

The red clay stain remover is a solid chemical agent that contains chemicals like sodium hypochlorite, which can be used to remove red clay stains simply because of its ability to cut through dirt quickly. You need to make sure that you apply it in small amounts since this agent can eat away at your brick’s protective seal if overused. If you use it, make sure to mix it with warm water before applying directly to the stains on your brick.

You can create a paste by mixing the stain remover with baking soda and then using it as a scrubbing agent on the brick surface. Always make sure to follow the instructions on the stain remover bottle and wear protective gear, like gloves and goggles, when using this chemical solution

9. Use a Sponge

You can remove red clay stains from bricks using a sponge since this is one of the most effective cleaning solutions available for this particular problem. The high concentration of soap in both hot and cold water makes this fluid a perfect solution to use for removing stains from your brick. The only downside is that the soap will render other cleaners less effective, so you might need to wait until after cleaning with a sponge before using any other chemicals on your brick.

It’s best to use hot water since it helps dissolve the red clay stains more quickly. You can also mix in some vinegar or hydrogen peroxide for added cleaning power and scrub with a sponge. Rinse off once finished and let dry before applying any other cleaning solutions.

10. Use Scrubbing Powder

Using scrubbing powder is another effective way of removing red clay stains because the scratches on its surface will allow it to provide a solid interface between your brick and the fluid you’re using. Because of this, scrubbing powder won’t just sit on top of your bricks but instead penetrate its pores where you can then use your soft bristle brush to remove any remaining particles easily.

Using scrubbing powder is another effective way of removing red clay stains

Following the instructions on your scrubbing powder bottle is essential since overuse can lead to corroding your brick’s surface. It’s best to mix it with warm water and then apply directly onto the stain, leave it for a few minute, then scrub and rinse off.  It’s a quick and easy solution for removing red clay stains from your brick surface.

Do You Need to Use Professionals?

While these DIY solutions can effectively remove red clay stains from your brick, it’s important to remember that some situations may require the help of a professional. For example, if the stain has been on the brick for a long time or is too severe, it may be difficult to remove with household cleaners. In these cases, it’s best to contact a professional cleaning service that specializes in brick cleaning.

Additionally, if you’re not confident in your abilities to remove the stain without causing further damage to your brick, it’s always a safer option to hire a professional. They have the necessary tools and experience to safely and effectively remove stains from your bricks without causing any harm.

It’s also important to note that some homes have special types of bricks, such as historic bricks or glazed bricks, which may require specific cleaning methods. In these cases, it’s best to leave the task to professionals who are familiar with the proper techniques for cleaning these unique brick surfaces.
