My e-liquids are turning dark

Try the following:

Store your e-liquid bottles in a cool, dark, dry environment.


Think about how long the vape juice has been sitting in the tank - exposure to heat, UV and oxygen can cause e-liquid to darken over time.


Check what nicotine strength your e-liquid is - higher nicotine levels will oxidise faster and cause your vape liquid to darken more quickly.
Make sure your tank is nice and clean - any residue of old e-liquid can affect the new juice in the tank.


Check to see if the coil needs replacing (if it does, make sure you always follow our coil priming guide).
 

Please note:

Vape juice will darken over time, regardless of environment. Also, e-liquid that contains freebase nicotine has a shorter shelf life than nic salt based liquid due to the effects of oxidation.
