First, what you’d want to do is to remove and separate the coil from the battery, in this case, you have to twist the threaded connections to take off the coil from the vaporizer itself. Once you’ve secured the atomizer and the coil you’d want to do a bit of wiping especially around the threaded area and around the atomizer. Once you’re done wiping this area with a clean and dry paper towel you may now take a good amount of isopropyl alcohol and fill your empty container at least to a point where the coils can be soaked and proceed to submerge the coils into the alcohol-filled container and leave it for a couple of hours.
After the coils take an isopropyl alcohol bath you may give it a little shake which helps in ousting and dislodging those hardened build ups. After which you may take them out of the container and dry it with your paper towel, although as a tip, using a rubber air blower also helps remove thickened wax. After they’ve dried up you can use a small brush to lightly graze the coils and further remove those nasty buildups. Depending on how much material your coils have accumulated, you may repeat this process until you’re satisfied. Keep soaking your coils since steeping them in alcohol will help loosen up that wax concentrates. Once they’re cleaned, dunk them on another filled with lukewarm water and leave them out to dry, I usually leave mine for half a day.
After drying out your coils, you may replace the parts back again for one final touch. You’d want to attach the coils to a fresh set of batteries for your burn off, this is so that you’d burn some of the chemicals that could be left on the coils.
