Last time I did it, I just scraped it.
In the past, having removed manifold I used pressure washer with good result.
Let us know when you try the gizmo?

it should have a positive impact, but I have heard that sometimes it also damages sensitive parts
so I would like to clean it but I am not so sure
Automotive industry for ages is flooded with 'Snake oils".
Being from Albania you might want to google what that American phrase means.
That is why I am skeptic about stuff like that.
On the other hand - carbon build ups look ugly, but the engine seems to work with it fine.
Years ago I took off manifold on W124 with almost 300k miles.
The intake had several mm of buildup who I cleaned to my best, but it did not do any noticeable change how the engine performed.
This year I was swapping short block on OM642 engine and original intake at 180k had lot of carbon around the flaps.
I scraped it, but again - no difference in performance. Others report that carbon on those engines stop flaps from moving, what popped codes. Dealers do manifold replacement only as they don't have technology to clean the carbon.
Is your engine OM651? Those don't seem to have flaps where carbon can create problems?
We sure will feel better having clean intakes, but heck, those engines run in taxis for 1/2 milions km without opening manifolds.

mine is OM646, I don’t know if it has flaps
I have the “puff black smoke” that is upsetting me
the performance is ok because I am not trying to race with an 220cdi
thanks
