Beat me to it-that's correct. When you take your shirts to a cleaners, they are laundered and machine or body pressed.I think there's general confusion over terms: many people refer to "Dry Cleaning" shirts when then take them to their local "Dry Cleaner". The reality of course is that when you take your shirts in they're actually laundering them ... usually harshly.
Lately I've taken to doing it myself. I get better results but ironing 10 dress shirts leaves a lot to be desired.
