I use a HOT pressure washer (at a good distance, with a wide nozzle) to get all the big stuff off, and spray on the soap, and a nice soft bristle brush with a 6' handle to scrub.
There is mud in the yard between the concrete pad I wash stuff on and the place I park it beside the shop.looks good.... ...but you missed some spots on the tires.... ....
