Diesel fuel can stain concrete. Concrete is a porous material with tiny holes that allow liquids to seep in. If diesel is not cleaned up quickly, it can penetrate the surface and leave a noticeable stain. The longer the fuel sits, the harder it is to remove the stain as it settles deeper into the concrete. To prevent future stains, a concrete sealer can be applied to reduce the porosity of the surface.

Absorbent materials to soak up spills
Diesel fuel can stain concrete, so it's important to act quickly when spills occur. The longer diesel sits, the deeper it penetrates the concrete, making it more challenging to remove the stain.
There are various absorbent materials that can be used to soak up diesel spills on concrete:
Cat Litter
Kitty litter is a common home remedy for absorbing diesel spills on concrete. It can be sprinkled over the spill and left for a couple of days before being swept up. One source suggests grinding the litter into the stain and turning it into dust before sweeping.
Sawdust
Sawdust can be used in a similar way to cat litter, by sprinkling it over the spill to absorb the diesel fuel.
Powdered/Granular Absorbents
There are also commercial granular absorbents available, such as OS Oil Absorbent Powder, SpillFix, and New Pig, which can be used to soak up diesel spills on concrete. These products are designed to quickly and effectively absorb fuel spills, leaving surfaces clean and dry. They are often safe for use on water, too.
Poultice
A poultice is a paste that can be spread over the stain, covered with plastic, and left for 24 hours. The solvent in the poultice breaks down the diesel fuel, and the absorbent material draws it out of the concrete.
Laundry Detergent
Some people recommend sprinkling powdered laundry detergent on the stain and allowing it to be ground into the stain by traffic. The detergent soaks up the oil, and after rain, the stain is gone.
It is important to note that, after using absorbent materials to soak up diesel spills, the area should be cleaned with soap and water or a degreasing dish soap to remove any remaining diesel residue.

Using a poultice
Diesel fuel can stain concrete. Concrete is a porous material with tiny holes that allow liquids to seep in. If diesel is not cleaned up quickly, it can penetrate the surface and leave a noticeable stain. The longer the diesel sits, the more challenging it is to remove the stain as it settles deeper into the concrete's pores.
If you are dealing with a recent diesel spill, you can cover it with an absorbent material like cat litter or sawdust. These materials will soak up excess fuel, preventing it from seeping deeper into the concrete. Leave the absorbent on the spill for a few hours, then sweep it up and dispose of it properly, adhering to local regulations for hazardous waste.
If the stain persists, you may need to use a poultice. Here is a step-by-step guide to using a poultice to remove diesel stains from concrete:
Step 1: Apply the Poultice
Spread the poultice paste over the stain, extending beyond the edges of the stain by at least an inch.
Step 2: Cover with Plastic
Place plastic sheeting over the poultice and tape down the edges to keep it moist.
Step 3: Wait
Let the poultice sit for 24 hours. The solvent will break down the diesel fuel, and the absorbent material will draw it out of the concrete.
Step 4: Remove and Clean
Scrape off the dried poultice, then clean the area with soap and water.
Step 5: Test First
Always test any cleaning method on a small, inconspicuous area first to ensure it doesn't damage the concrete.
Step 6: Protect Yourself
When using solvents, work in a well-ventilated area and wear gloves and safety glasses for protection.
Step 7: Avoid Harsh Chemicals
While bleach or muriatic acid may seem like powerful options, they can damage concrete and should be used with caution.
Step 8: Clean Up
Dispose of the poultice material safely and give the area a final rinse with hot water.
Step 9: Seal the Concrete
Once the stain is removed or reduced, apply a concrete sealant to prevent future stains from setting in. Reapply a sealant every few years to maintain the concrete's resistance to staining.
Old stains can be stubborn, and it may not always be possible to remove them completely. However, by following these steps, you can significantly reduce their appearance and protect your concrete from future stains.

Bleach and other chemicals
Muriatic acid is another chemical that can be used to clean concrete. It can be purchased at Home Depot and is effective at brightening concrete and masonry, as well as cleaning algae and scum. However, it is important to use muriatic acid with care as it can be dangerous if the fumes are inhaled. It will also etch the surface of the concrete, leaving a noticeable mark.
Other chemicals that can be used to remove diesel stains from concrete include commercial concrete cleaners, which may contain microbes that eat away at the stains. Powdered laundry detergent, such as Tide, can also be used, especially in combination with hot water and a stiff-bristled brush.
In addition to these chemicals, there are also home remedies that can be used to absorb the diesel fuel and remove the stain. These include kitty litter, baking soda paste, and sawdust. It is important to act quickly when addressing a diesel spill on concrete, as the longer it sits, the deeper it penetrates, making it more difficult to remove.

Concrete sealers
Concrete is a porous material, which means it has tiny holes that allow liquids to seep in. If diesel fuel is spilled on concrete and not cleaned up quickly, it can penetrate the surface and leave a noticeable stain. To prevent future stains, consider applying a concrete sealer to reduce the porosity of the surface.
For indoor concrete sealing projects, water-based sealers are generally recommended due to their low odour and environmentally friendly characteristics. These sealers are nearly odourless and have low VOC levels, making them more environmentally friendly than other concrete sealers. Water-based acrylic sealers are also easier to maintain and can enhance the colour of the underlying floor. They are available in high-gloss and satin finishes, with the high-gloss option being ideal for highlighting the colour and shine of the concrete.
On the other hand, solvent-based sealers are UV-resistant, keeping the underlying concrete stain clear and vibrant. They also prevent moisture from penetrating the surface, making them ideal for outdoor concrete surfaces such as patios and pool decks. Solvent-based sealers are available in high-gloss and satin finishes as well, and products like EasyTint™ can be used on both indoor and outdoor surfaces, cutting the project time in half.
Some popular concrete sealer products include the Eagle 5 Gal. Natural Seal Penetrating Clear Water-Based Concrete and Masonry Water Repellant Sealer and the BEHR PREMIUM 1 gal. Wet Look Sealer, which can be found at Home Depot. Other options include the AcquaTint™ Tinted Sealer, AcquaSeal™ Water Based Sealer, and EasySeal™ Solvent-Based Sealer, which offer protective benefits along with added colour.
