How to clean e-liquid carbon buildup

 　　There are now endless e-liquid flavors on the market. Whenever a new one comes out, the questions vapers care about most are: does it taste good, and does it cause heavy carbon buildup?

  　　Whenever you see the heating coil covered with a thick layer of black residue and the cotton turned pitch black as if it were toxic, that is carbon buildup from e-liquid. So how does it form? As is well known, e-liquid mainly contains PG (propylene glycol), VG (vegetable glycerin), food-grade flavoring, nicotine, and various additives. Carbon buildup is produced when the heating coil vaporizes the e-liquid at high temperatures. The VG, PG, nicotine, and flavorings generally leave little residue after vaporization, but sweeteners in the e-liquid can produce some solid residue when heated at high temperatures, similar to caramelized sugar. In addition, condensed liquid can flow back onto the heating coil and be reheated, causing it to "burn on" and form buildup. That is what carbon buildup is. So, the sweeter the e-liquid sold on the market, the more severe the carbon buildup tends to be. When carbon buildup reaches a certain level, it may have adverse effects on human health.   　　So how do you clean carbon buildup? Take a cup of water, remove the cotton from the atomizer, heat the coil until it glows red, then dip only the glowing coil into the water (release the fire button first). Be careful not to submerge the entire atomizer base in the water. Repeat this several times to remove the buildup. If you want it even cleaner, you can gently scrub the gaps in the heating coil with a small steel brush, or simply replace it with a new coil.   　　Replace the cotton regularly and clean carbon buildup often—don't be lazy.
