i use, or rather used a DCT carto with my 6ml DCT
tank setup. I said i used because..... let me first tell you the
juice i used. i DIYed a concotion of RY4 and peppermint flavor with a 50-50 PG-VG composition, later after letting it steep for only a day or two, i tasted (read vaped) it and tweeked with some MTS vape wizard and sweetner. The result was good, the falvor was sharp caramel with mint, worked for me. Then i filled up my 6ml tank as i was planning a trip, but later realized that after a few toots, there was some dark liquid coming out of the hole punched in the DCT carto, by next morning my golden colored
juice was dark brown, i checked for it online and i can chalk it up to the caramelized suger, by the same evening i was not able to take a toot clearly with out some liquid getting in my mouth and the drags were very hard, i think so i screwed up my carto. Now the point is, IS there a way to clean it and re-use the carto or i can say i murdered one.

any help is welcome.
