How To Prevent Coil Gunk: The Best 4 Tips

Vape coil gunk is something all vapers have to deal with, but it doesn’t have to be something they battle every day. That’s why we decided to create this blog, to tell you about the four main reasons why coil gunk occurs and four of the best tips to avoid coil gunk for as long as possible. So, if you are ready, let’s get started.

What is Coil Gunk?

Coil gunk is the leftover vape juice that does not evaporate. It includes the sweeteners, the flavorings, and other ingredients of e-liquid. They are created directly on the coil, hence the name coil gunk, and after a time, become dark and solid. They look like solidified drops on the coil and get thicker if they are not clean, or the coil is replaced. They also tend to damage the wick.

As you might expect, this can become expensive after a while. Replacing coils and wicks is not fun, and if coil gunk occurs more often than you would like (sometimes happening in a single day) and with the price of coils costing anywhere from $2 to $3, it could start hurting your pocket. 

Now that you know what coil gunk is, you can probably identify it on your coil. If you are currently experiencing too much coil gunk too often, below you can find the best five tips to prevent this from happening. 

Avoid High VG E-Liquids

Although coil gunk is unavoidable, there are things you can do to slow it down or make it less likely to happen. For example, one thing you can do is avoid high vegetable glycerin e-liquids. As you probably know by now, the two most important ingredients in vape juice are vegetable glycerin and propylene glycol. 

Propylene glycol is more like a liquid and is responsible for carrying the flavor and giving your throat that burning sensation that makes vaping have that similar throat hit as cigarettes. 

Vegetable glycerin which is responsible for giving you a smoother throat hit is a whole different story. Instead of acting like a liquid, vegetable glycerin is a very viscous substance that is heavy and is slow to evaporate. 

If you are currently vaping on a vape juice that has a higher vegetable glycerin content higher than 70%, it is very likely that this is the reason why you are experiencing quick coil gunk build-up. In fact, if you currently use a pod system or low-powered vape pen with a vape juice that has a high vegetable glycerin content, then this is definitely the reason why you have coil gunk. To fix this, try switching to a different ratio, perhaps a 50VG/50PG ratio which will be ideal. 

Sweeteners in Vape Juice

Another reason why you might be experiencing coil gunk buildup is that the vape juice you’re using has too many sweeteners. Dessert, fruit, and candy-flavored vape juices tend to have sweeteners that enhance and create the flavors. However, this also has the unintended effect of easily clogging your coils with coil gunk. This is because, just like with vegetable glycerin, these vape juices tend to be thicker and more viscous than tobacco-flavored vape juices. 

The other reason is that artificial sweeteners like sucralose don’t evaporate and instead caramelize on the coil creating coil gunk again. To avoid this, researching vape juices that don’t use sweeteners in their recipes is your best bet. You can also avoid dessert, candy, and fruit vape juices altogether and instead settle for using tobacco and cigar flavors or more neutral flavors that don’t use sweeteners. 

Avoid Dark E-Liquids

Another possible culprit responsible for creating coil gunk is dark e-liquids. Some people say that dark e-liquids, which always tend to be sweeter (which means they use sweeteners) rather than light e-liquids, have a tendency to create more coil gunk. And while there are dark e-liquids that are not sweet, there is something to be said about the components that make them dark, which might be responsible for making them more likely to create coil gunk. 

Avoid Flavored E-Liquids Altogether

Something you could do is avoid flavored e-liquids altogether and switch to unflavored vape juices. Unflavored vape juice has zero artificial flavorings, zero sweeteners and only has the three most important ingredients: vegetable glycerin, propylene glycol, and nicotine, which can also be optional. 

The advantages of unflavored vape juice are many for example; you don’t have to worry about any possible side effects that artificial flavorings might create; you can choose from a wider variety of nicotine levels since there is more space in the formula for higher amounts of nicotine, and most important of all, they create less coil gunk. 

Although there are formulations of unflavored vape juices with high VG that might cause coil gunk, these unflavored vape juices without artificial flavorings and sweeteners are purer and easier to use vape than flavored vapes, which leads to less coil gunk buildup.

Conclusion

Coil gunk is inevitable, but there are ways to avoid it for as long as possible. To recap, you could switch to unflavored vape juices that have zero artificial flavorings and sweeteners (the number one cause of coil gunk), you could also buy light-colored vape juices, which some people say are more prone to creating coil gunk, or you could also move to a higher PG vape ratio since a higher VG ratio is more likely to cause coil gunk build up. All in all, these are four excellent ways in which you can fight coil gunk on your terms without allowing it to take over your device and your pocket.
