Selecting the Right Brush

The success of your scrubbing effort depends heavily on the tool in your hand. You should avoid brushes with soft bristles, such as those made from natural horsehair or fine synthetic nylon designed for sweeping household dust. These are far too gentle to penetrate the textured surface of concrete and will simply glide over the top of the stain.

Instead, look for a heavy-duty scrub brush featuring stiff, stiff-synthetic or natural Palmyra bristles. A long-handled deck brush or push broom with stiff bristles is especially useful because it allows you to stand upright and apply downward body weight into the scrubbing motion. The bristles need to be rigid enough to flex into the tiny pits and trowel marks of the concrete without bending flat against the surface.

For older stains that have completely dried, you can gently sweep the area, but no pre-soaking is necessary yet.

Applying the Cleaning Agent

The choice of cleaner depends on how long the oil has been sitting on the concrete. For minor, recent spills, a generous squirt of concentrated liquid dish soap or heavy-duty liquid laundry detergent works well because these substances are specifically formulated to break down grease and oil molecules. Pour the soap directly onto the dry stain, ensuring it completely covers the darkened area.

For stubborn, aged stains, create a thick paste using dry powdered laundry detergent and a small amount of warm water, or use a mixture of trisodium phosphate and warm water following safety precautions for skin and eye protection. Alternatively, covering the stain in a thick layer of baking soda and letting it sit dry for a few hours can draw out some of the oil before you even add liquid. Once your chosen cleaner is resting on the stain, let it sit undisturbed for fifteen to thirty minutes.

Rather than scrubbing in a single circular motion, which can simply move the loosened oil around in a circle, use a vigorous back-and-forth scrubbing motion across the grain of the concrete texture.

Rinsing and Inspecting the Area

Once you have thoroughly scrubbed the entire stained zone, do not let the dirty soapy residue dry back onto the concrete. Immediately flood the area with clean water from a bucket or a garden hose. As the water flushes the surface away, use the brush once more to sweep the dirty water toward a drain or off the edge of the slab.

Inspect the concrete closely while it is still wet, and then let it dry completely to get an accurate assessment. Water can sometimes mask remaining oil, making a stain look gone until the concrete dries out. If the outline of the stain is still visible once the area is fully dry, it means some oil remains trapped deep in the pores. You will need to repeat the process, perhaps using a stronger cleaner or allowing the cleaning agent to soak for a longer duration before bringing the stiff-bristled brush back to work. For deeply ingrained stains that have survived multiple scrubbing sessions, a poultice method using an absorbent powder mixed with a solvent may be necessary to draw the remaining petroleum out from beneath the surface layer.
