Suggestion
Wet abrasive blasting is favoured for the removal of carbon deposits and for other engineering "cleaning" applications (such as aerospace magnesium castings) because it is very unlikely to embed microscopic particles/ contaminants into the parent material.
Leading evidence: 'Clean by ben at vapour blasting brisbane' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Clean " applications (such as aerospace magnesium castings)' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Incidentally, the machine shop I use also use a similar cleaner to clean up the heads and components that they work on.

So not wanting to scare you, and heads 'might' be fine, however camboxes and engine cases I would not consider, just chemical cleaning only
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

What I'm referring to is what is know as silica embedding into the pores or galleries of engine parts, yes the same pores that absorb oil, oxidization and many other contaminants, to clean that off, all abrasive blasting methods use some form of grit, this grit gets into pores of cast aluminum or other hard to reach areas, and is extremely hard to remove......except when cycles of heat and vibration occur...meaning when your lovely new engine is running, the grit then goes around then engine and causes seriously accelerated wear and premature failure

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Thanks Dave for the scientific explanation as well, i wondered how it worked.
I just had some cylinder heads and cylinders cleaned by Ben at Vapour Blasting Brisbane.. Hopefully the pictures will work here...

Though that finish looks great, and I reckon heads may be safe-ish I would tread carefully on any grit based blasting

I'm no expert, but the 928 community knows this issue well when people try and blast their intake runners / plenums with some form of grit based blasting
It's laboriously discussed in this thread

Totally agree with you Rob.
Incidentally, the machine shop I use also use a similar cleaner to clean up the heads and components that they work on. Not sure exactly what type of media it is though...
The media used is Spherical glass beads, which can be used both in wet (vapour blasting) and dry abrasive blasting. Wet abrasive blasting is favoured for the removal of carbon deposits and for other engineering "cleaning" applications (such as aerospace magnesium castings) because it is very unlikely to embed microscopic particles/ contaminants into the parent material. It has also HSE benefits as respirable dust is almost eliminated.
Cheers,
Dave
Can vouch for Ben's work, and he's a real car tragic (often at C&C in all manner of different things)

This is a source reference. Confirm exact model applicability in the original material.
