Hydrogen Carbon Clean vs Walnut Blast

[philt91]

Anybody on here had a hydrogen carbon clean done? My car is needed a carbon clean and the hydrogen clean is only £99 as opposed to £290 for a walnut blast, not sure if the hydrogen clean is going to do the job as good but and they cant show you the end result as they don't take the head off the engine?

Id be interested to see the end results of the Hydrogen clean, the Walnut blasting removed 100%.

don't know if u went ahead with the hydrogen carbon clean, but we tried it on the 207's here in Scotland and was a complete waste of money.

maybe cleaned the turbo and intercooler a bit if anything, but did hee haw to the inlet valves.
