About two weeks ago I made a lot of juice. I had some old nicotine I wanted to get rid of, so I made a base to mix with 7% flavourings to give me a nice 80/20, 3mg vape. And because I love it so much I made myself a whole 50ml bottle of Vanilla Butternut (just plain FW VB). It was a freshly washed and air-dried bottle. Today it was good to go and I put a new build in my Plume Veil, soaked the wick well, hit the fire button and inhaled ...
harsh...
bitter...
with a hint of apple?!
Apple indeed, from the washing up liquid I had used on the bottle.
Lesson learnt: Don't just wash your bottles, rinse them extra thoroughly.
TIL that someone, somewhere, calls soap "washing up liquid".
At least in the UK, yeah. Soap is for hands and bathing, washing up liquid is for, well, washing up. Pots and pans and stuff.
Caandian here, we use 'soap' as a general term, but 'handsoap' is what's by the bathroom sink and 'dishsoap' is what you wash pans out with.
I actually had to read this post a couple times to realize what was going on.
If I can actually try to contribute for OP for a second, I actually don't 'wash' my bottles at all. I rinse them pretty thoroughly, and thats about it. For plastic bottles, I just try to use a similiar juice as what was in before, since leaching seems fairly permanent from my experiments.
I also rinse (with hot water) and leave to air dry. Something I find helps a lot though is to get a little water in the container, seal the container, and then shake the water in it. If you see small bubbles or suds it requires further rinsing. Once the container is removed of impurities and only tap water remains in it there will be no bubbles or suds with violent shaking.
Oh, that has to suck... Was the batch completely ruined?
Friend I know who was cleaning attys at a vape shop built an atty, dripped, hit it... to realize that simple green hadn't been cleaned off of it. Gave him a crazy head ache.
I am OCD and paranoid so I go overboard. I keep my old used bottles in a pile until I get around to cleaning and rebottling them.
First, I take the bottles, pour some "washing up liquid" in them, shake it around until suds form, then rinse it thoroughly.
Then I take the bottles and submerge them in boiling water for about 10 minutes.
After that, I take them out, put them on a cookie sheet and throw them in the oven at 340F for about 45 minutes.
Out comes sterile bottles (of course which are instantly contaminated since I don't live in a clean room).
PSA: If you boil your bottles, use distilled water unless you want a chalky substance forming on them.
I like to fill my bottle with rubbing Alcohol and let it sit for couple hours ( pretty sure 10 min is enough ) then wash bottle out couple time and dry it . Removes all flavors. The pharmacist must think I am a crazy alcoholic with death wish with how much rubbing alcohol I go through ( drinking alcohol is heavily control here, need permit to purchase it from liqueur company). Use it to clean everything from RDA to syrings.
Rubbing alcohol would kill you if you ingested it
i dont even take the cap of my little 10ml bottles when I rinse them, I just suck up the water by squeezing the bottle while the tip is under the stream of water from the sink, give it a good shake and repeat once or twice... never had a problem with cross contaminating....
