I think my chain cleaner is a Finish Line brand, a little less expensive than Park, but has worked fine for me. Now that the degreaser that came with it is gone, I use Simple Green full strength. After I clean the bike and the chain, I show up to my rides so proud of my shiny bike, which lasts for all of 30 seconds on the trail! But I really think it extends the life of the chain and makes shifting better, so it's worth the effort. It's a good investment, especially if you have 5 bikes in your garage to maintain!
