Wow, lots of replies while I was writing, thanks all of you.
I thought I'd have hubby go outside and dunk the rolls in a bucket of water to eliminate the airborne stuff, then transfer inside to the sink. I do wear a mask for things,I was just surprised by the amount of dust/lint balls in there this time!
I've read that in the books too, that you shouldn't wash, but I have had to ignore that for so many things due to my allergies and most things come out fine, however, with most things I'm not worried about losing 1/4" from shrinkage so this is totally different! Thought I'd ask if anyone has any real experience. I'll send them back if there is a good chance of them shrinking.
Looks like that might be the safest thing to do.
