Nice and detailed video. It's a tedious process without the walnut blaster, but the results are quite similar. By curiosity, have you ever tried to use gasoline as carbon cleaning/removal ?
Thank you! I haven't tried gasoline, but I think it will work. It is likely not as effective as acetone or xylene, though. I really like xylene - it smells not that bad as acetone and is very effective, especially if you soak in it for several hours.
