    Facing the same problem. Power washer – no good. Bleach and TSP with power washer – minor progress. A paste or strong suspension of Oxyclean and water with a stiff plastic brush – well, doesn’t quite just wipe right off, but scrubs off pretty quickly. Got the porch stairs and railings in about an hour, the rest should take about the same.
