Have you ever been enjoying a vape, and suddenly the e-liquid tastes strange, dry, or even a bit burnt? Well, that could be due to coil gunk — the archenemy of all vapers!

This problem not only makes the flavor unpleasant but also forces you to change your coil frequently. Annoying, right?

So you don't keep wasting money on new coils, let's first understand what coil gunk is, its causes, and effective ways to avoid it!

What is Coil Gunk?

Coil gunk is a sticky black residue that builds up on the coil's surface due to unvaporized e-liquid. Over time, this gunk prevents optimal e-liquid flow, dulls the flavor, and can even cause the cotton to burn quickly.

It usually appears because the e-liquid doesn't vaporize completely or because certain ingredients in your e-liquid leave a residue. It might seem trivial at first glance, but its effects can be detrimental to your vape's flavor and performance!

Causes of Coil Gunk You Must Avoid

Before we talk about prevention, it's really important to know what makes coils get dirty quickly. Here are some of the most common causes:

1. E-liquids That Are Too Sweet and Dark in Color

Sweet-flavored e-liquids are tempting, but unfortunately, the artificial sweeteners in them often don't vaporize completely.

These sweetener residues stick to the coil, gradually harden, and burn into black gunk. Dark color = a warning sign for your coil!

2. High VG E-liquids

High VG (Vegetable Glycerin) indeed creates thick and very satisfying vapor. But on the other hand, high VG e-liquids are thicker, so the coil has to work extra hard to absorb them.

As a result, the e-liquid doesn't vaporize completely and eventually turns into gunk.

3. Vaping Too Intensively

Who here likes to chain vape without a break? This habit keeps the coil hot without rest, burns the cotton, and turns leftover e-liquid into gunk. If you use high wattage and like long draws, the risk of coil gunk is even higher.
