As a NYC rider I would say that's the correct diagnosis. Everything turns black here, and oil attracts all kinds of dirt. I only skimmed the thread but did see someone mention Squirt wax lube, which is what I use now. It stays a lot cleaner but you need to apply it regularly. I can handle the chain without having black stains on my hands for a week after. And it makes it very quiet.
