I have run my c 27's lines (exept the wire to rope halyards) through the washing machine at home 4 times in the past ten years with no noticeable ill effects. I've never used a bag or special soap. I just heap them in, throw in some tide as usual and they come out looking spectastic, tangled but spectastic. I don't think i'd reccomend the dryer though.
