I'm certain that this topic has been addressed in this forum, but with limited time to search I've not been able to find the discussion. Â I'm at wit's end trying to preserve the double-thick buttons on a number of my English dress shirts. Â I usually launder my shirts and have them ironed without starch. Â But I often get my shirts back with cracked and fraying buttons. Any suggestions on what I should instruct the cleaner to do? Â I do not have the time to handwash and iron my shirts. Â If there is a previous discussion of this topic, I'd gladly accept directions to it. Thanks in advance for your suggestions.
