We had a tree near our house significantly trimmed. Unfortunately as the tree was being cut the branches must have hit parts of the side of the house leaving orange marks ( it's a Carrotwood tree known for yup, orange wood). I have tried gentle and firm hosing , after light scrubbing with dishwasher soap and warm water, but the strains aren't coming out and they are pretty unsightly. Any ideas? I am nervous about ruining the stucco which was just redone last year.
