My engine has high mileage, looking down the spark plugs holes there is clearly carbon on top of the pistons its a dark thick'ish coating, why would you want to get rid of carbon? Promotes detonation.
Now I'll put my flame suit on...
I dribbled water down the brake booster line as soon as it reached the intake manifold you could hear it turning to steam and probably expanding, I ran probably half a small cup into the vac line not rushing it and keeping the revs high. The exhaust onto a piece of paper expelled speckles still this may not have been carbon.
Result, well the top of the pistons have now a light brown coating instead of a dark black and this is when it was time to stop as I don't believe you should have no carbon. You can use sea foam which is probably stronger but I'd rather not have it eat away at seals.
I regularly change my oil so It seems regular oil changes and good fuel do not keep them crystal clean.
One word of caution you can hydro lock your engine if you put too much water in as obviously you can't compress water. You will foul your spark plugs a little, also a small amount of water can pass through an engine no problem. A concern of mine was dislodging chunks of carbon and them getting stuck and reducing the seals caused by carbon helping but I don't think it's strong enough. Checked the oil and there was a tiny tiny bit if mayo as to be expected.

This was actually a tried and tested method that was always used, as a quick de-coke method when a car was suffering from pinking, detonation as you call it now, good on you for reviving it, today they do have sprays you can buy for this some are water based,
i don't under stand Dixon's reply is it to pour scorn on the OP,or his lack of understanding, I find the link to the audi thread totally irrelevant to this topic,
