Pour cat litter onto the gasoline. Cover the entire stain with cat litter and continue to pour on more litter in the areas where the litter is quickly absorbing the fluid. Leave the cat litter for 24 hours to absorb the gasoline. The litter will neutralize the gasoline and can then be swept away using a dustpan and brush.
Pour dry cement mix onto any remaining gasoline. The smaller particles in the cement mix will react with and absorb any gasoline the cat litter was unable to soak up. Cover the gasoline with the cement mix and allow it to sit for 24 hours. Sweep up the cement mix with the dustpan and brush.
Mix up a stiff paste of baking soda and water. Pour a small amount of water over any gasoline that is still present on the driveway. Apply the baking soda paste to a scouring brush and scrub the dampened gasoline. Rinse away the gasoline and baking soda mixture with more water.
