Hello all, I am only a DIY’er in the sense that I mix American eLiquid Store’s 100% VG (30%), with their same flavor/nic of 100% PG (70%) because they have huge sales on 100% VG only. So, I’ve got all the different sized graduated cylinders, blunt-tipped needle top plastic bottles, etc. They recommend refrigeration only (not freezing) their juices, for extended storage up to two years. I’ve got a fairly large stash now in my fridge, bought a large amount of various blue cobalt glass bottles of various sizes from Specialty Bottle a while back and am now ready to begin the transition into the glass for storage. My question is: what is the best way to sterilize them? I bought various sizes/shapes of all different kinds of cleaning brushes from Amazon, but have heard mixed opinions in here (washing twice, etc.). Specialty bottle does not have any thing on their website about sterilization. So I just got off the phone with Specialty Bottle and the nice woman who answered explained to me the following: - Their bottles have not been sterilized in any way before they’re shipped. Furthermore, she explained that they’ve been sitting in cardboard cartons in their warehouse, which is not a sterile environment, and most likely have accumulated dust particles in them. - It depends on how you intend to use them. So I explained that I’m using them for storing electronic cigarette e-liquid, to which she didn’t have any specific answer for that application. - She said the bottles can withstand up to 90 degrees above room temperature, and that of course boiling them would be much hotter than that, and that they couldn’t guarantee that the bottles wouldn’t shatter. - She suggested researching how to sterilize them properly. A simple quick search of sterilizing amber medicine bottles yielded very little. A search for sterilizing canning jars seems to point to boiling (no good). Does anyone have any suggestion or insight here, as to how we can do this? If we really need to do this? If not (or just as a pre-step to sterilization), I’m fully equip to begin a rigorous washing regimen on them. Any help with this question would be greatly appreciated, as I’m trying to get that task done today! EDIT: additional email reply from Specialty Bottle regarding my inquiry: "Hello, Thank you for your email. The bottles are washed after the manufacturing processes however when they are packed up and shipped, they are subject to dust and debris. You may want to wash the bottles after you receive them. The bottles are dishwasher safe however the caps are not. you may want to wash those by hand. Please let us know how else we can help you today" Again, all suggestions welcome!
