The “iron-y” (pun intended) is you could pretty much buy a new one of those cheap M and H shirts after every use for what a lot of dry cleaners charge to clean them.
I generally do my own because, believe it or not, I can do a better job cleaning the collar with some “Shout”, some bleach, and a little elbow grease than most of the dry cleaners do. It seems that most of the time they leave at least a little brown residue...
