Before I had a pressure washer, I would use a hose and a spray nozzle of some sort. I ended up getting an electric power washer to foam my car and rinse it off. I prefer the pressure washer but the hose is quick and easy to do since I don't have to move a lot of stuff or set up much.
They make different tips, maybe need to find a different tip that has more pressure to rinse because the pressure washer rinses fairly well.
