Why does my vape juice turn dark or brown?
Vape juice turns dark or brown for two reasons: the sugars in the e-juice have caramelized from heat exposure or the e-liquid has expired from oxidation. You can determine the cause of your e-liquid turning dark brown by tasting it. Caramelized e-juice will have the same flavor as normal juice but will have a thicker texture than usual.
Why does my e-juice get dark?
When e-juices get darker, it means they’ve been stored improperly or exposed to excessive oxidation. If you notice dark, gunky stuff in your vape tank or on your coil, it’s time to switch out your e-juice bottles and clean out your tank. Ultimately, to avoid any problems, you should be storing your juice in a cool dark place.
