Removing diesel fuel stains from concrete can be a challenging task. Concrete is porous, allowing diesel to seep into its tiny holes, which can result in a stubborn stain that resists cleaning. However, several methods and products can effectively remove diesel fuel stains from concrete, including Petro Buster, which breaks down the tension between petroleum and water, making it possible to dissolve and wash away the stain. Other suggested methods include using detergents, such as laundry detergent or dish soap, and absorbents like cat litter or floor dry to soak up the diesel fuel and lift the stain. In some cases, more aggressive approaches, such as using phosphoric or hydrochloric acid, may be considered, but these can alter the appearance of the concrete surface.

What You'll Learn
Use a detergent
If you want to use detergent to get diesel fuel off concrete, there are a few different methods you can try. Firstly, it's important to note that detergents work better with hot water. You can try using a detergent such as Dawn Ultra dish soap to suds the area and then power-rinse it. Alternatively, you can try squirting some detergent onto the stain, adding a small amount of water, scrubbing with a stiff brush, and then rinsing thoroughly.
If you're dealing with a larger area, you may want to look into renting a power washer with a detergent attachment. This will allow you to cover more surface area and more effectively remove the stain. You can also try using laundry detergent, such as Tide, by sprinkling it onto the stain and letting it get ground in by traffic. This method may take a bit longer, but it can be effective in removing the stain.
Another option is to use a combination of detergent and other products. For example, you can try using a detergent with an engine degreaser to lift the diesel, and then scrub and rinse. You can also try using a detergent with baking soda, vinegar, or kitty litter to help absorb and remove the stain.
It's important to note that there is no one-size-fits-all solution for removing diesel stains from concrete. The effectiveness of these methods may vary depending on the age and severity of the stain, as well as the specific detergent and tools used. It may take some experimentation to find the best method for your particular situation.

Try a pressure washer
If you want to try a pressure washer to remove diesel fuel from concrete, there are a few things to keep in mind. Firstly, it's important to act quickly as old stains can be more difficult to remove. If the diesel spill is recent, you can try using a detergent or a specific cleaner like Poultice Plus on the affected area before pressure washing.
Before pressure washing, it's recommended to use a stiff brush or broom to scrub the area and let it sit for a few minutes. You can also try using a combination of water and a detergent or dish soap, such as Dawn Ultra, to suds the area before rinsing with the pressure washer. If you're using a detergent or soap, ensure that you rinse thoroughly to remove all residue.
When using a pressure washer, be cautious as the high-pressure water stream can etch or remove the thin top layer of concrete, especially if it's smooth. This can result in an unsightly appearance where the cleaned area differs from the surrounding surface. If you're unsure, test the pressure washer on a small area first to see how the concrete reacts.
Additionally, consider using hot water with the pressure washer as it may be more effective in removing diesel fuel. If the stain is particularly stubborn, you may need to repeat the process, scrubbing and rinsing multiple times until the stain is no longer visible.
While pressure washing can be effective, it's worth noting that there is a range of other methods to remove diesel fuel from concrete, including the use of specific chemicals, detergents, and absorbents.

Apply an acid
To remove diesel stains from concrete, one method is to use an acid-based cleaner. However, it is important to note that not all acids are suitable for this purpose, and some may damage the concrete or be unsafe for the environment.
One acid-based product mentioned is Petro Buster, which is mixed with water in a 4:1 ratio and applied to the stain. This product is designed to pull the stain out of the concrete surface. Another product mentioned is Green Safer Muriatic Acid from Klean-Strip, which is intended to brighten concrete and masonry by etching the surface.
When using any acid-based cleaner, it is essential to follow the manufacturer's instructions and take the necessary safety precautions, such as wearing protective gear and ensuring adequate ventilation.
Before applying any acid, it is recommended to try other methods first, such as using a detergent or pressure washing, as acid can be harsh and may not be necessary for all stains. Additionally, some sources suggest using kitty litter, baking soda, or sand to absorb the diesel before attempting to remove the stain with a cleaner.
If you choose to use an acid to remove the diesel stain, test it on a small area first to ensure it does not cause discolouration or damage to the concrete. Apply the acid according to the manufacturer's instructions, allowing it to sit for the recommended amount of time before rinsing or neutralising it, if necessary.

Soak up with sand or kitty litter
If you're looking to remove diesel fuel from concrete, one effective method is to use sand or kitty litter to soak up the spill. This is a great way to address the issue, especially if you're concerned about the impact of chemicals on the environment. Here are some detailed steps and tips to guide you through the process:
First, it's important to act quickly. The sooner you start the cleanup process, the better your chances of successfully removing the diesel fuel from the concrete. So, if you have sand or kitty litter on hand, get to it!
For sand:
- Generously cover the spill with sand.
- Use a broom or brush to work the sand into the stain. The goal is to have the sand absorb as much of the diesel fuel as possible.
- Leave the sand on the stain for several hours or even overnight.
- Sweep or brush away the sand, disposing of it appropriately.
- If a stain remains, repeat the process as needed.
For kitty litter:
- Spread a thick layer of kitty litter over the diesel spill.
- Grind the kitty litter into the stain using your feet or a heavy broom. The friction will help break down the diesel and absorb it into the litter.
- Let it sit for a few hours or overnight.
- Sweep or brush away the used kitty litter, ensuring safe disposal.
- If necessary, repeat the process until the stain is gone.
If you're looking for an even more powerful absorption method, you can try using a combination of sand and kitty litter. Simply mix the two together and follow the steps for using sand, grinding the mixture into the stain and letting it sit before sweeping it away.
While using sand or kitty litter can be effective, it's important to note that it may not completely remove the stain. The diesel fuel can penetrate the concrete, leaving a discoloured area. In such cases, you may need to consider additional treatments or power washing to fully restore the concrete's appearance.

Use a specialised product like Petro Buster
If you're dealing with a diesel spill on concrete, a specialised product like Petro Buster can be highly effective at removing the stain and eliminating the fuel smell. Petro Buster is a plant-based, biodegradable product that's safe for the environment and can be used on hard surfaces like concrete.
To use Petro Buster effectively, follow these steps:
- Prepare a mixture of Petro Buster and water at a 4:1 ratio. This means mixing four parts water to one part Petro Buster.
- Use a garden sprayer to apply the mixture generously to the affected area of concrete.
- Scrub the area vigorously with a stiff-bristled deck brush to work the product into the concrete and create a rich lather.
- Rinse the area thoroughly with water and observe the colour of the suds. If they are still dirty, reapply the Petro Buster mixture, scrub again, and rinse until the suds become clean and white.
- Allow the concrete to air dry. You should notice a significant improvement in the appearance of the stain within a day or two. For slight remaining stains, you can reapply, scrub, and let it dry again.
Petro Buster works by breaking the tension between petroleum and water, making the petroleum water-soluble and allowing it to emulsify. This process helps to remove both the stain and the smell of diesel fuel from concrete surfaces. It's important to follow the instructions provided by the manufacturer and to wear appropriate protective gear when handling any cleaning chemicals.
