Tormek lists its paste as 3 microns so it is a bit courser than the green stick but they both give a high polish. The Tormek paste is a little faster due to the slightly larger grit. I have used them interchangeably and could never really tell the difference in the finished edge. 8000 grit or 30,000 grit, either way it takes more microscope than I have to see the difference. I have never cleaned between the two except maybe a quick wipe with a dry cloth to get rid of the little black junk that clutters up the wheel after use.
