I have seen various tips on how to do this and many suggest using a pressure washer. However, I have also read that using a pressure washer can damage the wood and can wash out preserver from pressure treated timber. After cleaning, I will be applying a wood treatment but want to get the fence clean before I do this. Are specialised cleaners any good for removing algae? Any advice welcome.

I would go with the pressure wash if you intend to retreat the fence anyway.
Leave it till summer so it can dry thoroughly before treatment.
