Has anyone tried using a Mr. Clean Magic Eraser to clean a fly line? I'm sure it would do a good job of cleaning as they will clean darn near anything. I actually used one to clean the lake scum off the side of my aluminum jon boat. However, I have no idea what chemical is imbedded in them so am a little concerned it could damage the line. They would be handy to use as you could easily cut one in two and carry it in your vest.

Any thoughts?
