This car has never had a carbon cleaning, less than 40k miles, but that doesn't mean anything. There could be gobs of carbon in there. My car had lots of carbon buildup - worst I've seen yet - when I did it at 47k miles last year. Whenever he schedules another appointment, we agreed that carbon cleaning would be the next step. It's regular maintenance, anyway...
