Dont know if this will get moved but I figure this is the best place for this. I recently realized I have "missplaced" my favorite daypack so I gotta pull out some of the oldies but goodies. Both have been stored for a long time and are nasty dirty with mildew smell but they are solid packs with alot of life left. I was wondering if they could be machine washed? I was thinking about putting them in a zippered pillow case on the delicate cycle. I have a front load washer so its pretty gentle. If not what is your best routine for cleaning nasty packs?
