RLM leader computes the log segments to be deleted based on the remote retention config. It updates the earliest offset for the given topic partition in RLMM. It gets all the remote log segment ids and removes them from remote storage using RemoteStorageManager. It also removes respective metadata using RemoteLogMetadataManager. If there are any failures in removing remote log segments then those are stored in a specific topic (default as __remote_segments_to_be_deleted) and user can consume the events(which contain remote-log-segment-id) from that topic and clean them up from remote storage.  This can be improved upon in later versions. 

RLM follower fetches the earliest offset by calling RLMM.earliestLogOffset(tp: TopicPartition).Both leader and follower cleanup the existing indexes till that offset and updates start offset with the received value.
