So we've been using our ego c set up about five months now and we love them compared to the 808's and smaller 510 setups we used previously. We use type B low voltage atty's with all ma sizes of twist batteries. Our atty's last 5 to 10 days and I have a bag of 20 or more used atty's that id love to learn how to clean. Ive boiled....soaked in vodka....and tried flushing with water. Had okay results occasionally but stopped trying to clean them as they just didn't last or taste good often enough to makenit worth it. I don't really even use the vv on the twist and am wondering if we should try standard atty's or change the vv. We are pretty happy with the system but there is always room for improvement. We have tried the Dolores cartos and prefer the standard setup we use to them. Any advice? I read through some cleaning ego c post and even though we have been vaping a year allready I'm not totally up to date on what all the abbreviations and equiptment names are ore mean.
