String algea on wood how to remove for new tank

[Ninjascape]

Hi,
I am closing down a tank and have a lot of large drift wood. The wood is covered in string green algea. I can pull off the large clumps but it's anchored to the wood in loads of places.

I have scraped one with a spoon and dried for a month seems alright.

Anybody have tips tricks to remove this. It's come from eBay and destroyed my old tank aquas ape quite abit of money I really had to save up.


Anybody have any ideas
