No, my chain is not "clean", just like the underside of my car, the bottom of my shoes, and the sewage pipe of my toilet are not "clean". There are some devices in the world that are not meant to be operated "clean".
Just because a machine can operate dirty, doesn't mean that is optimal. Introducing dirt into a moving machine increases wear and friction. It is less efficient, has a shorter lifetime, and is more likely to malfunction. A chain is "meant" to be run as clean as possible.
Do you know how much of my life I have wasted on keeping my drivetrain "clean" during this 4300 miles? Grand total of maybe 5 minutes.
Look, it's your bike. Abuse it if you want. No skin off my back. But your bike would run more efficiently and last longer if you spent more than 5 mintes every 4300 miles cleaning the drivetrain. I'm sure there are people who never change the air filters in their HVAC or change the oil in their cars, too.
