I used to use a similar system. However, as the number of flylines began to build it became a time consuming nuisance. I now use any of the fly line cleaners on the market (Renew, Loon, SA, and a bunch more) to clean the line while it's stretched out between a hook on my porch and a tree. I find that these cleaners clean every bit as well as soap and water, and I then have the line in the position I want to add Russ Peak dressing. I add the RP, let it dry in the sun while I do other chores for about twenty minutes, and then use a clean cotton rag to buff the line. What I get is something far better than any line straight out of the box. I still have a few lines left from the late 1960s that are in wonderful shape because they are cleaned and dressed on a regular basis.
