yeah ittis are nice lol they dont run like the others, so safe to wash together
you can do what squishington said about soaking them or run them thru a few rinse cycles
i wash on 60 and theyve never had a problem
just dont tumble dry the outers, it can cause pul probs (they shrivel) the inserts shouldnt be tumbled but if you find they go stiff when dry a quick 10 mins in the dryer on a low heat will soften them up
