I use the Park cleaner myself, but since I went to a wax lube the chain doesn't get nearly as dirty. You need to apply it more often but it really makes for a quiet and clean ride. You can run your hand over my chain and not have a semi-permanent tattoo on it, just a little smudge. Squirt brand is what I'm using, specially designed to do exactly this. I apply every 100-150 miles on two different bikes.
