 ## Description
 
 
-This command cleans up any data associated with a replica. It is useful for cleaning up garbage in case of failures or to uninstall DTR. For scaling down a cluster see the remove command.
+This command forcefully removes all containers and volumes associated with the given DTR replica without notifying the rest of the cluster. Use it on all replicas when you want to uninstall DTR.
