how are you going to clean it?

Manually. Remove the intake then scrub and pick it clean.

Oven cleaner?
These are my thoughts and opinions - sometimes I'm wrong, but not often ;-)

We have just  started using hydrogen/oxygen for  carbon cleaning in Wellington.
The machine is from taiwan and beautifully built.
We can be found in contacts under  www.carbonclean.co.nz/contact-us/
The process works very well as hydrogen and oxygen atoms are smaller than carbon
therefore, gently clean away the areas affected by carbon.
There are some engines prone to heavy contamination  therefore, we recommend
a 2 step process. 1. chemically injecting an atomised spray  and 2. finishing with the
gas (hydrogen/oxygen). Results have been great to date and we have done a good
range of audi/vw product.   walnut blasting is effective however,it is only treating the intake.
Our process completely cleans the intake manifold. valves,pistons,injector face and combustion
chamber,turbo which are  cleaned  gently to restore what has been  incrementally lost.
We therefore restore and gain back power and fuel efficiency !.

If it works, it works and I wish you well - but pseudo-science, and incorrect "science" at that as a carbon atom is smaller than an oxygen atom*, doesn't instill confidence.

depends how you define "bigger"

iirc high school chemistry...

going from left to right elements have more atomic mass, so oxygen wins

but carbon has a larger atomic radius - size, so a win for carbon

Interesting, things have moved on since my high school chemistry lessons from (way) back in the day - I would had assumed the outer valance shells to have been the same size - or slightly larger, if anything, due to a larger nucleus.
[edit] More protons, stronger attraction to the electrons, maybe? Anything on isotopes being the same or different?

As previously suspected. Hydrogen carbon clean does sweet FA for intake carbon build up on a direct injection motor.

Any of you looked at the Seafoam stuff, seems to be quite popular in Yankland?

asked an experienced mechanic about this, reckons it's not good but mechanics will do it anyway if the customers wants the cheap option, it does apparently do the job however it may also reduce reliability and longevity, in particular the around the seals - an example I heard was a customer with a holden commodore who came in wanting the quick cheap method - sea foam was used, 10,000km later the customer came back complaining that the engine is using oil

I disagree, i have seen a  gti 's intake after having a pre-chem treatment and hydrogen treatment and it most certainly does
have a cleaning effect on the  throttle body,combustion chamber, valves,injector face,spark plugs  and oxy sensor.

Got a cheap endoscope and had a peek into my intake. Looks like I'll be giving it a clean soon. It looks pretty dirty in there.
Are you opening it to clean it? can you do a before and after pic?

I am planning on it yes. I will document my experience. At this point it will probably only happen over Christmas though when I can afford to have the car off the road for more than just the weekend.

looking forward to see it.
Do you know any shop who do them?
