Just started using a kanger aerotank and I was wondering if the atty's can be cleaned or not. I was using 30s' s which I could easily clean and reuse but not sure about the new kanger coils. They're completely encased or appear to be (though I suppose they can't really be since the juice has to get in there somehow). So, anyway, if anyone out there has cleaned one before I would appreciate knowing how. Thanks.
