Query: Cleanest Chain In Years

I used a waxed base lube for years, and found that after a while, it the chain will not come clean because wax simply won't clean off with most bio-cleaners. I never cleaned the chain except with a rag because wax cleaners were supposed to "shed dirt."That was then, before I knew how clean a chain could be. This unit is well made, holds the chain steady with a stout handle, and has little mess compared to using a brush and rag.See my photos and you can see that the chain is shiny clean after running the chain through. You do one two cycles - the first to get the grime off, the second for a "rinse cycle."Great tool, great (as always) Park Quality. If you have a lot of bikes to maintain, this is a great way to go.
