Drives, forecourts and yards with oil staining
An oil stain is not the same as algae, and treating it the same way wastes time. Fresh stains lift more easily, while old ones soak into porous block paving and concrete and may fade without vanishing. We use a degreaser first, then rinse, and we are honest about how much improvement is realistic.
On commercial yards and loading areas, water containment matters. Surface water drains often lead to streams and rivers, and the Bridgewater Canal and Ship Canal are not far away. Capturing or limiting oily run-off is part of the plan.
