Removing Oak Seedpod Stains on Wood Deck

[OlDirty 14]

I have a new deck that I stained a few months ago with ReadySeal - looked great - but now seedpods have fallen on it from an overhead oak tree, were rained on, and appear to have melted into (for lack of a better word) little turds that put greenish brown stains all over the deck. Any idea on the best way to remove these stains? Its PT pine deck surface.

Thanks!

If the customer will pay I would try safe wash. If not just wait and it will get less worse. I have a customer with oak trees and they sit on the deck all winter and tannins leach out of the leaves and produce patterns on the deck. It is nature. Also the pressure treated tends to pick up more stuff than the harder woods
