Special Delivery and Orvis's Line Slick weren't meant to be a cleaner, merely a temporary silicone coating to help a sticky line. Fishing in the Louisiana marsh gets your line gritty and of course saltwater makes your line sticky. Usually the silicone coating is gone in less than thirty minutes of fishing, but great casting while it adheres. You still have to clean your line daily after fishing the salt with a good washdown and drying procedure.
