How to clean up gasoline spill on concrete

Gasoline spills on concrete can be a serious environmental and safety hazard that require prompt attention. Whether it’s a small drip from your car or a larger spill, it’s important to act quickly and effectively to contain the mess and minimize any potential damage. Concrete is a porous material that can readily absorb gasoline, allowing it to seep deeper over time. Failing to properly clean up a gasoline spill on concrete can lead to lingering odors, stains, and even fire or explosion risks if the vapors build up.

In this article, we’ll walk you through the step-by-step process for safely and thoroughly cleaning up a gasoline spill on concrete surfaces. We’ll cover the essential safety precautions, the necessary materials and equipment, and the proper techniques for effective cleanup. By the end, you’ll have the knowledge and confidence to tackle a gasoline spill on your driveway, garage floor, or other concrete areas around your home or business.

Safety First: Protecting Yourself and the Environment

Before you even think about starting the cleanup process, it’s crucial to prioritize safety. Gasoline is an extremely flammable and volatile substance, so you need to take the proper precautions to protect yourself, your property, and the surrounding environment.

Here are the key safety steps to follow:

  1. Eliminate ignition sources: Make sure there are no open flames, sparks, or sources of heat anywhere near the spill. Turn off any electrical equipment, appliances, or vehicles that could potentially ignite the gasoline vapors.
  2. Ventilate the area: Open windows, doors, or use fans to increase airflow and dissipate the gasoline vapors. Avoid working in an enclosed space.
  3. Wear appropriate personal protective equipment (PPE): At minimum, you should wear chemical-resistant gloves, safety goggles, and sturdy shoes or boots. Consider also wearing a respirator or mask to avoid inhaling the fumes.
  4. Control the spill: If the spill is ongoing, try to stop the source and contain the spread of the gasoline as much as possible using absorbent materials like kitty litter or sand.
  5. Notify authorities if necessary: For larger spills or if the gasoline has entered a storm drain or waterway, contact your local fire department, environmental agency, or hazardous materials team right away.

Gathering the Cleanup Supplies

Now that you’ve secured the area and are prepared to safely handle the gasoline spill, it’s time to gather the necessary cleanup supplies. Having the right tools and materials on hand will make the process much more efficient and effective. Here’s what you’ll need:

  • Absorbent materials (kitty litter, sand, or specialized spill pads/socks)
  • Degreasing or cleaning solution (dish soap, all-purpose cleaner, or specialized concrete cleaner)
  • Stiff-bristle scrub brush
  • Buckets or containers for collecting the contaminated absorbent
  • Plastic bags or drums for proper disposal
  • Wet/dry shop vacuum (if available)
  • Paper towels or rags
  • Flashlight or work light

If you don’t have all of these supplies on hand, you can easily purchase them from your local hardware store, home improvement center, or online retailers like Amazon. Here are some top-rated options to consider:

  • XSORB Universal Spill Kit – Includes absorbent pads, socks, and other cleanup supplies in a convenient kit.
  • Krud Kutter Concrete Cleaner – A heavy-duty degreasing solution specifically formulated for concrete surfaces.
  • DEWALT 6-Gallon Wet/Dry Vacuum – A powerful shop vacuum for quickly removing any remaining liquid.

Step-by-Step Gasoline Spill Cleanup on Concrete

With your safety gear on and all the supplies ready, you can now begin the process of cleaning up the gasoline spill on the concrete. Follow these steps carefully:

Contain the spill: If the gasoline is still actively spreading, use the absorbent materials like kitty litter or sand to create a barrier around the perimeter of the spill. This will help prevent it from getting any larger.

Absorb the bulk of the spill: Liberally apply the absorbent materials directly onto the gasoline. Use a shovel or your hands to work the absorbent into the concrete, ensuring it soaks up as much of the gasoline as possible. Scoop up and dispose of the contaminated absorbent properly once it’s saturated.

Degrease and scrub the concrete: Mix your degreasing or cleaning solution with water according to the product instructions. Dip your stiff-bristle scrub brush into the solution and vigorously scrub the affected concrete area. This will help break down any remaining gasoline residue and lift it from the surface.

Rinse and repeat: Once you’ve given the area a thorough scrubbing, use clean water to rinse away the degreasing solution and any loosened gasoline. Inspect the concrete to see if any staining or odor remains, then repeat the scrubbing and rinsing process as needed.

Vacuum up remaining liquid: If you have access to a wet/dry shop vacuum, use it to suck up any pooled liquid or residual moisture left on the concrete surface. This will help speed up the drying process.

Allow to fully dry: Give the cleaned concrete area ample time to air dry completely. This may take several hours or even a full day depending on the size of the spill and environmental conditions.

Dispose of waste properly: All of the contaminated absorbent materials, rags, and other waste from the cleanup must be disposed of properly, in accordance with local hazardous waste regulations. Contact your municipal waste management department if you’re unsure of the proper disposal methods in your area.

Tips for Effective Gasoline Spill Cleanup

To ensure the best possible outcome for your gasoline spill cleanup on concrete, keep these additional tips in mind:

  • Act quickly: The sooner you can begin the cleanup process, the easier it will be to remove the gasoline before it has time to fully soak into the concrete.
  • Use the right absorbent: Kitty litter and sand are inexpensive and effective, but there are also specialized absorbent products made specifically for cleaning up gasoline and other petroleum spills, such as the Pig Grippy Absorbent Mat.
  • Scrub thoroughly: Don’t be afraid to really work the degreasing solution into the concrete with your scrub brush. The more elbow grease you put in, the better you’ll be able to lift out the gasoline residue.
  • Check for lingering odors: Even after visually cleaning the area, use your nose to detect any remaining gasoline smell. If you still detect fumes, keep scrubbing and rinsing until the odor is fully eliminated.
  • Ventilate the area: Continue to keep windows and doors open, and use fans if possible, until you’re confident the gasoline vapors have been fully cleared.
  • Dispose of waste properly: Improper disposal of gasoline-contaminated materials can have serious environmental consequences, so be sure to research and follow the correct hazardous waste handling procedures. Consider using a specialized hazardous waste disposal service like Veolia Environmental Services.

Preventing Future Gasoline Spills on Concrete

Once you’ve successfully cleaned up a gasoline spill on your concrete surfaces, the next step is to take proactive measures to prevent future spills from occurring. Here are some tips:

  1. Regularly inspect and maintain your vehicles: Regularly check for any leaks or drips from your car, truck, or other equipment and address them promptly to avoid spills.
  2. Use spill containment mats or trays: Place absorbent mats or shallow trays under parked vehicles to catch any drips or small spills before they can reach the concrete. The Lumax LX-1632 Spill Containment Mat is a popular and effective option.
  3. Improve concrete sealant: Consider applying a high-quality concrete sealant or epoxy coating to your driveway, garage floor, or other concrete areas. This will help make the surface less porous and easier to clean in the event of a future spill. The Rust-Oleum RockSolid Concrete Coating is a great choice.
  4. Store gasoline properly: If you need to keep gasoline on your property, such as for a lawn mower or other equipment, make sure it’s stored in an approved, leak-proof container in a secure, well-ventilated area. The Scepter 5-Gallon Gasoline Can is a durable and safe option.
  5. Educate yourself and others: Learn about the proper procedures for handling and cleaning up gasoline spills, and share this information with family members, employees, or others who may need to address a spill on your property.

By taking these proactive steps, you can help minimize the risk of future gasoline spills on your concrete surfaces and be better prepared to handle them effectively if they do occur.


Cleaning up a gasoline spill on concrete requires prompt action, the right safety precautions, and a systematic approach to effectively remove the contaminant and prevent further damage.
