Being a relative newbie I am starting to wonder what to do in terms of cleaning my tanks. I have iClear 30s and Protank 3. When they get low on juice and I'm ready to switch to another flavor do I just rinse them out and go from there, or is there a preferred method of cleaning? Trying to avoid having 1 flavor bleed into the other, new flavor. I did a quick forum search here but didn't find anything.

Welcome!
+1 on the others' replies. I will also pull my coils and drop in a bit of unflavored vodka (or everclear, but I can't drink everclear

) for a few hours or overnight. I don't have quick access to all the links, but google Dry Burning for your specific tank type. This will show you how to remove some of the burnt-on gunk (especially from higher VG and/or darker juices) and refresh the coils to be reused. I've been vaping for about 3 months now, and am still using almost all my original coil heads - but I've been rotating them in and out through about 10 different tanks.)
I just ventured into the world of rewicking and rebuilding my heads (EVOD/mini ProTank 2/Smok Aro (pyrex)) tanks, so I'm single-coil about 95% time. I have a couple iClear 16 tanks and iClear 30 tanks that came with my VV3 and MVP2s. I just rinse well with hot water, and drop in the vodka. Rinse again after soaking, and let air-dry (I'm finding that it's helpful to "prime" the wicks with some juice before I load them into the tanks - just keeps me from having to wait as long for the wicks to saturate before firing.)
For the tanks themselves, I just run under hot water and let air-dry.
If I'm at work, and don't have a fresh coil, I'll rinse under hot water or suck up the wicked flavor change
glad you've joined the ranks!
