Most of the crispy texture is just salts and maybe algae growth. Throw the line in a big bucket and use laundry soap. Churn it with your hands, soak over night, churn it some more. Rinse and drain. The water will be astonishingly filthy. Why not try a baking soda rinse as well. I finish up with a Downy fabric softener rinse and several fresh water rinses. The Downy really does a great job and my mainsheet smells daisy-fresh! Actually, this works great and you get to fondle your mainsheet up close and personal. Imagine, stroking it makes is softer! <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" />
