No cleaning is required if only the fruits were collected. If collected with other material, use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. Seed set and seed viability can be low. Seed viability can be low.
