You can either rinse them and lay them on paper towels to dry or if there is a lot of pulp put them in a container,cover them with water,let them sit 2 or 3 days until a fungus like mold covers them. Pour the mold and seeds that are floating off the top. Put in a fine colander or sieve and rinse until clean.Drain, Put on a single layer on paper towel lined plate. Stir daily til dry and that's all there is to do it. Hope This Helps.
