The last thing I use is 000 then 0000 grade steal wool and twist it in the bowl to smooth everything out. I forget to get a pic of this process but this is the piece of steal wool I used.



I will also take a piece of steal wool, unravel it flat, and run the top of the bowl over it on a flat surface a few times to smooth out any scratches.

Here is where I decided enough was enough.



For the most part, I cleaned the stem like I would any other. Scrubbed with pipe cleaners and alcohol until it came out pretty clean. Soaked in Oxyclean and water for 24 hours and then went at it with an Arm and Hammer Magic Eraser to remove any crud. With vulcanite I may have continued with micro finishing cloth abrasive pads but did not feel it was necessary with this stem.



Here is where we are up to this point.
