Yo Vapo (sir or Ms.?) use that methos once a week to clean my used cartos (and something really awesome to dry them), works very well. When you vape 13ml's a day, and on average a carto needs cleaning after the 5th-6th refill, go through at least 2 cartos a day. If I didn't clean them would be going through 60 cartos in a month... That severly cuts into the batt and juice budget... Which is equally as high oddly enough...
