Vape coils are one of the most crucial parts of an e cig build but are often overlooked. With a range of materials and shapes, it is one of the only parts of a vape device that can be found inside every single product, regardless of the brand.

Whilst they may come in different designs, the coil is an important aspect of vaping to get your head around.

So, when it comes to vape coil upkeep, one question that always comes up is that of longevity. Vape coils are most often made of metal, which means that they are subject to heat reactions and could potentially rust.

When browsing an online store or vape shops in Southend running an e liquid clearance sale, you’ll no doubt want to have a look at vape coils, too. With this guide, you’ll know what you’re looking for, what to avoid and how to take care of any products you purchase.

What does a vape coil do?

Vape coils are vulnerable to heat and liquids because, well they constantly interact.

The coil acts as the connection between the battery of your device and the atomiser. Electricity is transformed into heat and travels down the coil to heat up your atomiser. This, in turn, heats up and vaporises the wick soaked vape juice which is replaced by the liquid in your vape tank.

Is that rust or gunk on my coil?

Vape coils are exposed to e liquids and heat. When your coil starts acting up, the first clue to the heart of the problem is whether it is being caused by a juice build up or a rusted coil.

This is vital to figure out because one cause is manageable, whilst the other means you’ll have to replace your coil.

How to tell the difference?

A simple dry burn test will do the trick.

If you suspect your coil’s having trouble, either because it’s looking rusted or blackened, then try emptying your vape tank of liquid and powering up your empty device. If the heat produced begins to melt away the extra juice on the coil, then you’ll know that it’s vape gunk build up causing your vape coil to look rusted.

If you’re still faced with a burnt taste, then you’ll know it’s a problem with your coil and it could be rust.


If you’re a little obsessive over your vape device, then you might find yourself giving it a clean more often than needed. As you may know, cleaning out your vape components simply involves taking apart the device and dousing each part separately in warm water. But, if the coil is exposed too often to water, it can begin to degrade and rust.

To minimise damage to your device’s coil, wash it only with very mild soap or with none at all.

Bad metal

Whilst most vape companies strive to make their coils as high quality as possible, a rotten apple might get through. Making sure you buy coils from only reputable sellers to avoid purchasing a component that has a far shorter lifespan than is advertised.

Exposure to liquids

Some liquids may be prone to reacting quicker with your coil, especially if they’re low quality.

In most cases, the juice will run out before it affects the coil. But, if you’re a light vaper and manage to sustain yourself with one tank’s worth of vape juice for several weeks, then you might see the coil degrading over time.
