cleaning cedar siding

I have a customer who wants her siding cleaned. She has stained cedar siding that has light green mildew on one end of the house. The siding is very lite grey and will be stained again soon. What would be a good process for removing this mildew ? I haven't done much cleaning of this type. Thanks everyone !

Sometimes just water. You can use soap, bleach and water mix. Be careful to water down and watch out around the grass and bushes.
