Myvapesite: Your guide to better vaping
It's the classic question of every vaper: “How often do I actually have to change my coil??” The short answer is: It depends on. It depends, how often you vape, what e-liquid you use and how you handle your tank. On average, a sub-ohm coil lasts between one and two weeks.
But you don't have to throw it away immediately, as soon as the taste subsides a little. In this article we will show you, like her Burnt taste (Dry Hits) avoid, Save money and even be able to clean your coils.

When does the coil need to be changed??
There are essentially two warning signs:
- loss of taste: The liquid tastes flat.
- Burned taste: You taste a coking note (Dry Hit).

- The tip: Stay in the middle range of the recommendation and take short breaks between long hits, so that the cotton can absorb new liquid.
2. Be careful “Coil Killern” (Sweet e-liquids)
We all love sweet desserts or fruity liquids. Unfortunately, these flavors are the biggest enemies of your sub-ohm coils.
why is that? Sweet liquids often contain a lot Sweetener (sweetener). When this is heated, it doesn't caramelize completely, but leaves behind residue. That dark crust, oft “Coil Gunk” called, settles on the heating wire and the cotton.
- The consequence: The coil becomes crusty, the taste is distorted and it tastes burnt, as the crust is reheated.
- Solution: If you love sweet liquids, you have to expect that, change the coil more often. Menthol- or pure fruit liquids are often gentler.

- Place the old coil overnight (ca. 12 Hours) in a glass with vodka or pure grain alcohol (no isopropanol!). The alcohol dissolves the incrustations and old liquid residues.
- Important: Then rinse the coil thoroughly with warm water.
- Allow the coil to dry completely in a sunny location (at least 24 Hours).
Notice: The coil won't “like new” be, but often much cleaner and tastes better.

A simple basic rule, which is often forgotten: Don't wait until the last drop, before refilling.
