OK......I may be a heretic or just a cheapskate.....but I use the Scientific Anglers product.....I think it is just called line dressing??

Anyway, I squirt it on the foam pad and run the line through it going off the reel and some more going back on and keep on fishing. Can be used with wet or dry line whenever the flyline starts to drag through the guides or you notice your casts are rougher, and shorter. Just a little shot and peel off 60 feet or so and go! Depending on how dirty the water is and how often I'm fishing I may clean the line and reel thoroughly, otherwise-FISH,FISH,FISH.
Works for me.
