Reading car forums, the overwhelming opinion is that a pressure washer

Road film is remarkably resistant to simply being blasted off. You
still need some form of rubbing to get it off, either a brush or
cloth. If just pressurised water was enough do you think automatic
car washers would have
great big rotating brushes?
