I just figured out a good way to get kief from the vape hose (DBV, SSV)..which could have been posted before, I'm not sure. Anyways When it's time to clean it, I take the two glass pieces off the hose, take a paper towel, put the single layer paper towel on the end of the hose and give it a hard pull. After I pull, there's alot of kief on the paper towel that just falls right off onto your desk or whatever surface you are using. You can try doing it a few times..I only did it 3 times and didn't get much on the 3rd pull so I stopped..I'm sure if you go a long time without cleaning it there will be a shit load!
