Ok so just now I broke out a clean carto, had them in a bag of rice since Friday, put juice in it, attached it to my PV, took a drag, nothing, no vapor at all. Is this what happens after u clean a carto, it stops working entirely??
According to the video I linked to, he says they come out about 90% as good as new after one cleaning. He says you can clean them about 5 or so times, I think. Did you dry them out well before you put them in the rice? I think they are supposed to be almost completely dry before the rice, and the rice will absorb what little moisture is left...
Are you getting any airflow through the middle? I have some cartos that got so gunked up that I couldn't even get any airflow. But, I still haven't gotten a syringe to try to clean them completely...
