+Node cleaning
+=============
+
+In Ironic *cleaning* is a process of preparing a bare metal node for
+provisioning. There are two types of cleaning: *automated* and *manual*.
+See `cleaning documentation
+<https://docs.openstack.org/ironic/latest/admin/cleaning.html>`_ for more
+details.
+
+.. warning::
+   It is highly recommended to at least wipe metadata (partitions and
+   partition table(s)) from all disks before deployment.
+
+Automated cleaning
+------------------
+
+*Automated cleaning* runs before a node gets to the ``available`` state (see
+:doc:`node_states` for more information on provisioning states). It happens
+after the first enrollment and after every unprovisioning.
+
+In the TripleO undercloud automated cleaning is **disabled** by default.
+Starting with the Ocata release, it can be enabled by setting the following
+option in your ``undercloud.conf``:
+
+.. code-block:: ini
+
+  [DEFAULT]
+  clean_nodes = True
+
+Alternatively, you can use `Manual cleaning`_ as described below.
+
+Manual cleaning
+---------------
+
+*Manual cleaning* is run on request for nodes in the ``manageable`` state.
+
+If you have *automated cleaning* disabled, you can use the following procedure
+to wipe the node's metadata starting with the Rocky release:
+
+#. If the node is not in the ``manageable`` state, move it there::
+
+    openstack baremetal node manage <UUID or name>
+
+#. Run manual cleaning on a specific node::
+
+    openstack overcloud node clean <UUID or name>
+
+   or all manageable nodes::
+
+    openstack overcloud node clean --all-manageable
+
+#. Make the node available again::
+
+    openstack overcloud node provide <UUID or name>
+
+   or provide all manageable nodes::
+
+    openstack overcloud node provide --all-manageable
+
+See :ref:`cleaning_workflow` for an explanation how to use Mistral workflows
+directly to initiate cleaning. This is particularly useful if you want to run
+some non-standard clean steps.
