I actually have no basis for this except it's what I do.
I use "Fantastik" "All-Surface" cleaner, which they claim at least, was designed for use on things like home electronics including computer terminals and flat screens. I figured if it wouldn't damage flat screens or high-impact plastics, it wouldn't damage painted carbon fiber.
I used it, with a soft rag, to remove all the government warning sticker glue from my carbon fiber bike. The paint and stopcoat show no sign of damage from this process.
