I can honestly say, I've purchased cartos from V4L for about 10 months and have only discarded approx 15 cartos (and that is a high end estimate).
I do what Scott does...sort of...
1) vape, Drip, and Switch:
vape until the flavor is not as strong, pop off the white end cap and add 4-5 drops...vape until the flavor is not as strong, pop off the white end cap and add 4-5 drops...etc...you get the drift.
After a week, I switch to fresh cartos and rinse the ones I've just used for a week.
2) Rinsing:
I pop out the end caps and just run the cartos under hot tap water until the batting looks white again. I blow the extra water out by blowing through the mouth end of the carto. I also rinse the end caps. I then set them on a paper towel upright to dry. By the time I'm ready to switch again, they are perfectly dry and ready to be filled.
I have not had a problem rotating through my cartos like this.
Thank-you. My rinsed ones may simply be too wet. Not touching them for a while. Most were all pre-filled and only 2 of my blanks failed, now.
Armed and ready for next order and just not trying it any other way now.
Take care.
