A driveway on Ruskin Street, Elwood, cleaned at the end of February. Driveways never soil evenly: the wheel tracks stay comparatively clean because tyres scrub them, while the centre strip and edges hold everything else. That unevenness is the difficulty. Clean it the wrong way and you finish with two pale bands where the tyres run.


A driveway carries two kinds of soiling and they do not come off the same way. Organic growth sits in the pores; oil soaks in rather than resting on top, so hosing it moves the surface film and leaves the stain. And a driveway slopes toward the street, so everything lifted off it heads for the drain.
Degreaser went on the oil first and was drawn out rather than washed along the slab. The rest was worked with a rotary head at consistent pressure across the whole area, wheel tracks included, so the finish came out even instead of banded. Run-off was contained and kept out of the drain — that is the part a fast job skips.
