Gasoline spills can be a messy and potentially dangerous situation, but with the right approach, you can effectively clean them up. Follow the steps below to ensure a thorough cleanup of a gasoline spill on concrete.

Step 1: Soak up the gasoline

The first step in cleaning up a gasoline spill is to quickly soak up the liquid. Grab a dry absorbent agent such as clay cat litter, sawdust, sand, straw, or dirt. These materials have excellent absorbent properties and will help neutralize the odor as well. Spread a generous amount of the absorbent agent over the spill, ensuring it covers the entire affected area.

Step 2: Let it sit

After covering the gasoline spill with the absorbent agent, allow it to sit undisturbed for at least 30 minutes. During this time, the absorbent agent will work its magic by soaking up the gasoline and reducing its presence on the concrete surface.

Step 3: Sweep up the absorbent agent

Once the absorbent agent has had sufficient time to soak up the gasoline, use a broom or brush to sweep it up. Gather the absorbed gasoline and the absorbent material and carefully dispose of them in a trash bag or a bucket designated for hazardous waste.

Step 4: Apply a cleaning solution

To remove any remaining stains and odors from the gasoline spill, it’s essential to apply an appropriate cleaning solution. Here are a few options you can consider:

Powdered dishwasher detergent:

Sprinkle powdered dishwasher detergent over the affected area, ensuring it covers the stain completely. Allow it to sit for approximately 10 minutes, allowing the cleaning properties of the detergent to penetrate the concrete. Then, use a stiff broom to scrub the detergent into the floor, working it in circular motions. Finally, rinse the area with clean water to remove any residue.

Baking soda paste:

Create a paste by mixing baking soda and water in a bowl. Apply the paste directly to the gasoline spill, ensuring it covers the entire stain. Let it sit for about 10 minutes, giving it time to break down the gasoline residue. Then, use a stiff brush to scrub the area vigorously, focusing on the stained sections. Rinse the area with water to remove any residue and reveal a clean surface.

Soapy water:

Prepare a solution of water and liquid dish soap in a bucket. Mix it well to create soapy water. Apply the solution to the gasoline spill, ensuring the affected area is thoroughly saturated. Use a stiff brush to scrub the area, working the soapy water into the stain. Once you’ve thoroughly scrubbed the spill, rinse the area with clean water to remove any soap residue.

Step 5: Dry the area

After the cleaning process is complete, it’s essential to dry the cleaned area. You can use a clean towel to blot the surface or allow it to air dry naturally. Make sure the area is completely dry before allowing any foot traffic or resuming regular activities.

Safety precautions

When dealing with gasoline spills, it’s crucial to prioritize safety. Here are some essential precautions to keep in mind:

  • Avoid using any heat sources or open flames near the spill, as gasoline is highly flammable.
  • Wear gloves and protective eyewear while cleaning up gasoline spills to prevent any contact with your skin or eyes.
  • Dispose of the absorbed gasoline and the cleaning materials properly, following local regulations for hazardous waste.


Cleaning up a gasoline spill on concrete requires a systematic approach to ensure effective removal of stains and odors. By promptly soaking up the gasoline, using an appropriate cleaning solution, and following safety precautions, you can restore your concrete surface to its original condition. Remember to exercise caution and prioritize safety throughout the cleanup process.
