Sealing and Protection After the stain is successfully removed, the concrete is in a vulnerable state, highly absorbent and susceptible to future damage. This agitation helps to lift the oil out of the porous capillaries.

The viscosity of motor oil or cooking grease allows it to lock deep within the matrix, making simple surface cleaning useless. For best results, allow the cleaning solution to soak for 10 to 15 minutes; this dwell time gives the alkaline agent the opportunity to saponify the fats, turning them into a water-soluble substance that can be rinsed away.
Applying a high-quality penetrating concrete sealer creates a hydrophobic barrier that repels water, oil, and other contaminants. A high-pressure power washer is the most efficient tool for this task, as the force of the water stream physically blasts the loosened oil particles out of the pores.
