How Do I Clean Gas From a Garage Floor?

A gasoline spill has the potential to create a very dangerous situation; gas is highly flammable, and the fumes cause dizziness and nausea. Cleanup methods vary by the size of the spill; a homeowner can manage a small spill.

Safely clean up gas spills.

Step 1

Unplug all electrical appliances, lights, lamps and radios. (A spark has the potential to ignite the gasoline fumes, causing a fire.) Shut off furnaces, stoves and any other machinery or appliances that have pilot lights. Extinguish lit cigarettes and candles.

Step 2

Open windows and garage doors for ventilation. Close doors and windows attached to interior home space to help prevent the fumes from penetrating and creating a more dangerous situation inside the home, as the fumes are highly flammable. Open interior windows in the home for gasoline fume ventilation.

Step 3

Sprinkle a thick layer of the cat litter over the spill and allow it to sit for 20 to 30 minutes.

Step 4

Sweep up the litter and place it in the fire-safe can. Move the can outdoors and away from the home. Call your local fire department for disposal instructions; every town and municipality has its own laws and ordinances regarding disposal.

Step 5

Apply the petroleum emulsifier or trisodium phosphate to the garage floor and scrub with the scrub brush.

Step 6

Rinse well with plain water.

Step 7

Repeat Steps 8 and 9 a minimum of three to four times.
