Saw a MicroG Pen on Craigslist for $20, seemed like a good deal and a good one to try out for my first vape. Used it for a couple weeks. it appears to have two air intake holes on the sides of the coil, which now seemed to be clogged with wax. This link says how to clean it, but not how to unclog the air intake. https://grencoscience.desk.com/customer/portal/articles/991064-do-i-need-to-clean-my-microg-pen- It says to stay away from the coil itself and don't soak anything in iso. Any ideas how to unclog the air intake? Was thinking soaking the coil in iso might do it, but would it damage it?
