I can not keep the same juice in all day I have two or sometimes three I like to use a day. My question is I have 4 tanks and I have several coils. I don't ever make it through a whole coil till I change the juice. I have been changing the coils out and putting them in a baggie with what juice was on them so I would know what they were and storing them. Is there a better way to do this or store them till I am ready to use that juice again? I have heard to put them in the freezer but just not sure that would be a good idea. Any suggestions from more of the experienced out there would be greatly appreciated on what I should be doing since I heard washing them out wasn't good for the either. Thanks for any help on this.
