Cleaning vinyl siding

We just purchased a doublewide mobile home that has vinyl siding; it needs cleaning/scrubbing but otherwise it's perfect. What's the best way to clean vinyl siding? We have a pressure washer but just looking at it makes me think it just needs some good ol' elbow grease. The back looks like it has green algae...need to cut cost as much as possible too. Thanks for your tips.
