How can you prevent the coil from oxidising?
To prevent premature coil oxidation, the golden rule is to always keep your coil well-saturated with e-liquid. Oxidation, which shows up as black gunk and a metallic taste, happens when the metal heats up in the open air or with a dry wick. You should also avoid vaping at a higher wattage than recommended for your coil to prevent scorching the components prematurely.
Light and ambient heat also speed up this natural process, so keep your tank away from radiators or direct sunlight. Remember to close your bottles and don't leave old liquid sitting in your tank for weeks at a time. In short, regular vaping and a well-filled tank are the best allies for a long-lasting coil. A pampered coil is the secret to flavorful vapor from the first day to the last.
