I'm new at this game and need some help with an equipment problem. I am using a Spinner and an Aspire ET-S glassomizer with a brand new coil. I vape 100% VG and filled two clearos with 2 different and new to me juices. In each instance, the clearos began to leak and each hit gurgled. The coils are new and this occurred within just a few hours of usage. What am I doing wrong? Is it possible to totally gunk up a coil in just a few hours? If so, are these coils now dead or can they be cleaned? Thanks for any wisdom!
