Who would have ever guessed??????"Never, ever use Saltwater on a Rio PVC fly line. It breaks down the bond and results in very poor durability. The line will dry out and harden with constant use in Saltwater. We recommend a mild soapy water with a flannel to clean the line, then if you want to re-lubricate it, apply a 100% silicone, though very lightly. All PVC fly lines use silicone as a lubricant, so it is best to use the base ingredient to prolong the line's life."
