I usually have more than one reel to clean when im coming back from a trip, and although the line winder can take two lots of backing, thats usually not enough and I hate the dance of moving things on and off. The perforations do make it great for cleaning fly reel backing. In my experience, salt in fly reel backing is one of the main causes of messed up reels, and it’s critical you strip and soak your backing after the tropics.
During one trip down the pool aisle in builders warehouse I spotted these yellow leaf trap things that looked a lot like the line winder tool and figured I could make one into a line winder. I did and they work beautifully. Here is a simple Step-by-step. Its a bit of work but makes cleaning lots of reels at once way easier.
