N.D.
there are dryer balls that you can throw in your dryer that will soften them up. i don't have them as i think (not having used them) that they soften your clothes by beating them up and would therefore make your clothes ages faster. but since it's for diapers, it can't hurt. i think i've seen these in grocery stores or asian markets:
