What techniques do you use to ensure the removal of deep-set oil stains from concrete without damaging the surface?

We remove deep-set oil stains by first assessing the concrete and testing a small area, then applying a suitable biodegradable degreaser with controlled dwell time before using hot-water pressure washing or steam at the lowest effective pressure. This staged approach breaks down embedded oil while protecting the concrete surface, joints and surrounding finishes from etching or unnecessary abrasion.
