Thanks everyone for your input on this. Here's what I have on the Dremel side of things, I have 2 small nylon brushes, the first one is just a straight brush and the larger one is a cone shape. They are both the same consistency of a tooth brush but, the bristles are smaller in diameter. These feel like they would take the rough high spots off the carbon, but not polish. The other two white round discs are more of a hard packed fiber material, but it feels like if they would catch an edge it would fray, but soft enough to do some final clean up.


I know my wife has some cooking pan cleaner around here so I'll ask her what she has. If not, I'll try and get some this weekend. Also, talked with our shop manager and he has a parts cleaner that will clean the head and valve but may not remove much of the carbon, but worth a try.

I'll post some pick this weekend to let you know the progress.

Steve
