I have heard of what Mal has said. Other options include running a little diesel in your gasoline (one qt per tank), Marvel Mystery Oil, or other such snake oils. I think all those might work as preventative measures after the initial cleaning.
Honestly, unless you're having symptoms of excessive carbon buildup (compression ratio significantly higher than spec, pinging under load when timing is sat, overheating at load...), I wouldn't worry about it! I found mine when I couldn't make the engine run smooth and quiet. I'm almost there now.
