Another woman who has posted to either push the hand washable setting on the machine or go to the drycleaner
If you like those pants, I don't know, why not consider starting your own dry cleaning business. I bet there are CLIENTS galore out there with the same concern about the distance to a decent dry cleaner that they are forced to wash in the sink or wear dirty clothes. Garments from wool, silk (ties, scarves, blouses), satin...think of the possibilities!
