My question is I want to Change my ejuice I've been vaping unicorn milk for about 3 days and now I can't taste it any more so im going to Change. I know I have to clean the tank and change the coil but my question is since the coil is still good can I keep it in a zip lock bag for when I switch back to unicorn milk or is it just trash now? Can you clean them? Also the juice im switching to is red bull flavor so I can't mix them.
