Grease, oil and equipment on concrete
Commercial concrete suffers differently from a residential driveway. Hydraulic fluid, diesel and motor oil soak into the surface, and plain water spreads the stain rather than lifting it. We use a degreaser first, let it work, then wash with hot or high-flow water where appropriate. Some old stains fade without disappearing completely, and we say so.
Wash water from a shop or yard needs care. Runoff may carry oil or chemicals, and local storm drains lead to creeks and lakes. We discuss containment and where water can safely go, and for larger commercial jobs we encourage you to check your own site rules as well.
