Manifold Cleaning

i have my a6 manifold and i wanted to start cleaning it since weather is nice outside, the manifold is out of the car, and its got some dust on it and other shit, im just wondering whats a good way to clean the outside and inside of a intake manifold, safely. Carb cleaner and a toothbrush acceptable?.....opinions and or comments welcomed

Engine foam, simple green... whatever, as long as you take your time on it it will look good. Carb cleaner is good at really eating through shit though.
