When I have done raggy quilts at home ( no laundromat in my old home town) I would take it outside and really shake it out after clipping. Then put it in the wash- with the load set larger than the quilt. After the wash cycle I stopped the washer and took it outside and shook it good again- then in for rinse- out to shake again then into dryer- out of dryer - empty lint trap & take it outside to shake again every 15 minutes until dry. It might seem excessive but I never clogged anything and they came out great.
