linespeedLoon Outdoors_Line Up Kit (Fly Line Cleaning Kit). I used the line cleaning tool and cleaner solution on two lines that I will be replacing after the trout season is over. So, this was a pretty stiff test as both lines were in rough shape.

The line cleaning tool is easy to hold and made it quite easy to apply the cleaning solution to the line. After drying overnight (as instructed), I buffed both lines with a cotton rag.

Several drops of the cleaner were enough to treat each line. I would expect this will last for quite some time.

Both lines showed marked improvement in sliding through the guides making it possible to shoot more line for long casts. After 2 ½ months both lines continued to perform well. Given that both of the lines were old and facing retirement, the line cleaning kit did a remarkable job of revitalizing the lines. I would highly recommend the kit.


  1. Hi Mike,

    Sure both were Scientific Angler’s master series lines. Both were cracked, dirty, and the tips were not floating all that well. After treatment, the flotation improved, but the increased casting distance was what surprised me most. Let me know if you want any other details.


    1. Thanks Joe. For cracked & caked lines I guess there’s little risk in trying anything at all, even if it might mean defeating the intended effect of micro-texturing. Mostly I wonder whether there are products that can be used on the “sharkskin” and “sharkwave” kinds of lines, during their non-cracked lives, to improve and extend their performance. Maybe this product is one such, maybe not. It would take a solvent that not only avoids changing the original properties of the material but also evaporates completely (like water does). I would guess alcohol would achieve the evaporation goal (and some petroleum distillates would too) but the goal of having zero effect on the line material is a bigger question. Maybe just mild detergent, as they recommend, but the problem is I never know how mild is mild–too mild and cleaning has little effect.

      I like the clamshell device on the one you have reviewed–looks easy to use.

      Thanks Joe,

  2. Hi Mike,

    I am a chemist by training. Generally they mean a reasonable squirt of dish detergent in 2-3 cups of water. The main thing is rinsing the line with clean warm water after using the mild detergent. That insures no film build up.

    When I used to clean my lines with mild detergent, I used an old white sock. If I didn’t see dirt in the sock after wiping down the line, I added more detergent until I did. I have never measured the detergent, but I would guess it is around 2-3 tablespoons in a quart of water. If you don’t see dirt after wiping with that, you either have a clean line, or need more detergent. I don’t think you can use too much detergent as long as you rinse with a sock rinsed in clean water.
