Note that cleaning is enabled by default on 4.7, but it wasn't in 4.6:

Comment 2 Derek Higgins 2020-12-02 16:07:32 UTC 
Automated clean was disabled because of a bug, https://storyboard.openstack.org/#!/story/2007229,
4.6 is using IPA python3-ironic-python-agent-6.4.1-0.20201103152810.7306c73.el8.noarch which contains a fix for the bug, https://review.opendev.org/c/openstack/ironic-python-agent/+/705062
So should be safe to re-enable auto clean, PR here https://github.com/openshift/ironic-image/pull/128
