Algae stains on Sunbrella covers.- How to get rid of safely

RStyleRStyle Posts: 1,603 Captain
My boat has a small tower and the cover has developed several lmoderate sized streaks of green algae along the sides.
Kept in a marina and looks ugly 🤷‍♂️
Only 4-5 yrs old and still waterproof. Tried to clean wild mild detergent and was then going to spray with 303 Fabric protector but they did not come out.
Is there anything that can be used that will not ruin the material and stitching?
