How to shift green algae from shed

ladykath

Hi, I wonder if anyone knows the best way to shift green algae from a wooden shed prior to re-painting with a wax-based preservative. I have seen a product for cleaning decking but it was quite expensive and I am worried about it reacting with the new preserver when I apply it later. I am thinking of trying a wire brush or a mild solution of Jeyes Fluid but have the same concerns about it reacting badly.
Regards, K

Hav youy got a pressure washer or can you borrow one? Very quick and easy. Plus because it only uses water, it wont cause any problems with the new preservative.
