I've used the Magmas a good bit -- they DON'T make the vape taste like perfume, trust me. Which would have nothing at all to do with why I tasted that perfume after I tried that juice that was in the squonk bottle, in my Achilles, and immediately tasted perfume -- there was a trace of SOMETHING in the DB 160 bottle that I identified as perfume -- whether it was some ejuice, or some cleaning product, I dunno, but I tasted it, it had nothing whatever to do with the Magma, which I've used a good bit, and it was horrible.
And yes, vinegar is a very foul and penetrating odor, which is easily absorbed by plastics, and can't then be gotten rid of, by ANY means. I've tried. It's not possible. I use vinegar for cleaning the rainbowed film and hard water deposits from stainless steel, because it's the only thing that really works -- but like other cleaning products, it's not really pleasant to smell, and lovely when you're done with it and can rinse it down the drain -- plastic hangs on to it.
