Ironing works, too. I've used it where clothes were sun/air dried, and of course insects laid eggs in the clothes. Insect eggs and the resulting maggots are why I don't air dry clothes any longer here. It is a personal revulsion thing for me, not a particular health issue here. Other places that I have lived, what hatches out would be a threat to your health.
At some level, if you are healthy, and those around you are healthy, and nobody is pointing out objectionable odors, air drying really an issue?
All the best,
Peter
