    I don't know, do know I'm lazy when comes to washing new bottles. Don't wash my new juice chubbies or bottles either. Mixed up 12 juices today and didn’t rinse out a single bottle. :shock:

    I rinse them in hot water, after I found some with cardboard bits in them.

    I prefer to wash my stuff just to be on the safe side, but I don't make a huge production out of it either. :) Just a quick wash and rinse.... :)

    I wash my glass nicotine storage bottles. I used to wash my plastic bottles before using them for my mixes.
    Now, I have enough that they are reused so washed after I empty them.

    I wash my amber glass nic storage bottles in hot water, rinse with steriliser, then rinse with distilled water and turned upside down to drain and dry for 24 hours before filling them almost completely full and placing them in the freezer.

    I use hot tap water to wash new and used glass bottles out before DIY. I rinse LDPE flavor bottles with cold or warm water before filling. LDPE gets pretty soft with hot water until they cool and dry.

    My LDPE bottles get filled with whatever is steeping in glass when it's time to make more juice. I just move the labels from the glass bottles to plastic bottles. The glass bottles get the newly mixed juice.

    I like to be able to monitor clarity and color change as steeping progresses in the glass bottles, but droppers can't beat thin tip LDPE for filling a tank through a small screw hole, so once juice is ready to vape it goes into LDPE thin tip bottles.

    A few posts back I reported opening a 1 liter amber glass bottle of Myfreedonsmokes 100 mg after 2 years in the freezer but a picture is worth a thousand words... If there is even the slightest change I'm not seeing it.

    Is that frost I see on that bottle?

    If so... I believe it is a mistake to open bottles of nic base before the have assumed room temperature because this allows condensation to form inside the bottle too, and mix with the nic base.

    Yes it's frost. The bottle was emptied into 4 smaller bottles as was the previous one. I've never bothered to defrost the mixing bottle for monthly mixing. After 2 years of mixing from cold bottles the nic showed no sign of color change.

    Preserving nic is about stockpiling which begs the question of how much to store and that partly depends on how many ml's will be consumed. I get some idea of that by paying attention to how long my 200 ml DIY batches last, which has been a month more or less in recent times. I'd also like to see what happens day to day, like the differences between work days and off days. So it occured to me I could use a graduated cylinder to make a measuring stick for the 20 ml dripper bottles I carry. The first step was to drip accurate measured amounts from a full bottle then mark the level, I used water and picked 3 ml intervals because I'd like to be vaping no more than 6 ml per day. (The last bit of liquid at the end measured exactly 2 ml showing that the bottle does hold 20 ml.) Marks on the bottle won't last very long so they will be transfered to a measuring stick.

    Most likely a syringe could be used in place of a graduated cylinder.

    I made up this little SS a while back. Just plug in 4 values and it will tell you your stockpile requirements.

    So it's been (2 days shy of) one year since I started this thread with the first two samples, and I suppose that means it's time for an update.

    As usual, I put all the samples in the fridge overnight so they would all be at the same temperature when photographed:

    [​IMG]

    I don't think they look much different than the last time I posted an update on these samples in October (bottom of page 12 of this thread).

    Here's what they look like against a while background in daylight:

    [​IMG]

    This seems to make subtle differences more apparent. The PG nic that's been kept in the freezer is still water-clear, while the VG based nic is just a darker, however the VG nic was already slightly darker when received (see post #78 in this thread). Interestingly enough, the room temperature samples look the opposite; the VG nic has darkened the least. @Kurt has long had the theory that VG's higher viscosity should slow oxidation, and I'm starting to believe it. Here are the samples I started with (post #1 of this thread). The first pic is with the sun behind some clouds:

    [​IMG]
    Followed almost immediately by the sun peeking out and providing much more light:

    The sample kept in the freezer has, IMO, the same slight straw color it started with, while the sample kept at room temperature has obviously oxidized a good bit.

    My general perception is that all the freezer samples are essentially unchanged from when I received them, while the room temperature samples have all darkened a lot, but the rate of darkening was highest early on and has now slowed. Perhaps all the available oxygen has been used up?

    I'm also going to reiterate my previous conclusion: Storage temperature appears to be far more important than whether the nic is in glass or PET plastic.

    Was there a taste test involved? Wondering how the real dark stuff tastes and vapes.

    No, in order to do that, I would have to open the bottles, which would ruin (or at least effectively end) the experiment.

    I'm sure that will happen at some point, but I'm not sure when.
