    Hard to see but if its like a dry flaky plant its lichen. You can use Wet and Forget outside formula on it.

    Appears to be lichen. You can remove this easily with a pressure washer.

    Apply Wet & Forget Outdoor with a garden sprayer. Dilute 1 part Wet & Forget Outdoor to 5 parts water. Apply Wet & Forget Outdoor to a dry surface in order to penetrate the stain completely. Saturate the surface completely with Wet & Forget Outdoor to remove moss, algae, lichen, mold or mildew stains.
