I would wash the deck first. What will be removed is dirt, grime and any residue that lay on top of the deck. If not removed then the sandpaper would “load up” that much quicker and make for sanding just that much more difficult. Washing and or pressure washing is an easy step to take both before and after sanding…good luck.
