Mine chamber only cleaned up completely with a dremel, which isnt advisable, my honda valves were metallic, though the head was darker than the stem.

Just leave it alone lol.

Re: valve condition ..

I think vinegar would probably do just as good a job. That's what I used to use to clean my rifle of carbon deposits after firing a few dozen rounds or so.
