Learn "Iron Out" in depth →The image behind the idiom
Picture an iron smoothing the last wrinkles in a shirt; this image helps explain the work phrase. People often use "iron out" for smaller problems in a plan or process. They do not often use it for work that has not begun, and it may sound too mild for a major failure that needs a full repair.
Outside work, "iron out" can keep its literal sense of pressing wrinkles out of cloth. It can also keep the same figurative sense as the workplace phrase, as in ironing out travel plans or a family schedule. The setting changes, but the idea of resolving small difficulties stays the same.
"A quick press should iron out the wrinkles in this shirt."
"We ironed out the travel details before the family trip."
"The supplier gave us an ironclad guarantee, and the new site director has a reputation for ruling with an iron fist."

The false-friend trap
Ironclad and "iron fist" share a root word with "iron out," but not a meaning. An "ironclad guarantee" claims a high level of strength or certainty, but it cannot ensure an outcome by itself. Someone who "ruled with an iron fist" used strict or harsh control. Neither phrase says that people resolved a problem.
