+=== Cleaning up removed services
+
+When services are removed from a nodeset's services list, their containers and
+configuration files remain on the data plane nodes. Use the `cleanup` service
+to remove these artifacts.
+
+The cleanup service tracks which services were previously deployed on each node.
+When executed, it identifies services that are no longer in the nodeset's
+services list and removes their:
+
+* Containers
+* Startup configuration files
+* Other configuration files
+* Service-specific artifacts (via cleanup tasks defined in each role)
+
+To enable cleanup of orphaned containers, set the `edpm_cleanup_orphaned_containers`
+Ansible variable to `true` using `ansibleExtraVars` on the deployment.
+
+The following example shows how to run a one-time cleanup after removing
+services from a nodeset:
