Question: [Wednesday, 18th Nissan, 5781]
Is it permitted for one to iron clothing during Chol Hamoed?
Yes. Many Poskim rule that it is permitted for one to iron clothing on Chol Hamoed [for the sake of Chol Hamoed or Yom Tov]. However, some Poskim rule that the custom is to avoid doing so, as perhaps the form of ironing which was allowed to be done is a very light form. Practcially, one who does not have a custom to be stringent may be lenient to do so.

Beir Moshe 7:89 rules that the custom is to avoid doing so, and those from Hungarian descent may not be lenient.
