Part 1: First action and causes

Motor oil on a concrete garage floor is a classic problem. Whether it's from a leaky car or a spilled quart during an oil change, the dark, greasy stain can be stubborn. The good news: you can often lift it with common household supplies like kitty litter and dish soap. This guide covers fresh and dried stains, with concrete-specific precautions.

What to Do First

Act fast if the spill is fresh. The longer oil sits, the deeper it soaks into the porous concrete. For a fresh spill, your first step is to contain it and absorb as much oil as possible.

How to Remove Fresh Motor Oil from Concrete

Contain the spill: Sprinkle a generous layer of clay kitty litter (the non-clumping kind) over the entire oil spot. Use enough to cover it completely.
Let it absorb: Leave the litter on for at least 30 minutes, or longer if the spill is large. It will soak up the oil.
Sweep it up: Use a broom and dustpan to sweep up the litter. Dispose of it properly.
Apply dish soap: Mix a few drops of liquid dish soap (like Dawn) with warm water in a bucket.
Scrub the area: Use a stiff-bristled brush or broom to scrub the soapy water into the stain. Work in a circular motion.
Rinse thoroughly: Rinse the area with clean water. You can use a hose or a bucket of water.
Repeat if needed: If a shadow of the stain remains, repeat the dish soap scrub.
