So im new to the vaping world and have just started out with refilling cartos... after a few fills i see the filling is brown in colour so i decided to wash a few of them out using hot water. After letting them dry for a few days and refilling them with my usual juice (100%VG) im getting little to no vapor. The carto still makes the hissing sound.
Am I doing something wrong?
