i haven't tried polycaf to try and clean atomizers (since i tried them once and then never again), but i'm really intrigued about the idea. i've worked in a cafe for coming up 4 years now, and i'm quite familiar with the product. i understand that the actual ingredients vary depending on your brand and where you live, but i'm guessing they're all pretty similar. the product i'm familiar with is edible, and though it doesn't taste awesome it's still safe for consumption in case there are some lingering residuals. it's also a cleaner that rinses away fairly easily. the act of backflushing an espresso machine is overall pretty passive, but again, the polycaf rinses away fairly easily even just backflushing an espresso machine on one rinsing cycle after one cleaning cycle. (for those unfamiliar, 1/2 tsp polycaf is added to a portafilter with a solid filter, then water is run once with the portafilter is attached, then once without an articulated portafilter. to rinse the polycaf one needs only feed hot water into the matchine with the portafilter attached, then once more unattached in order to thoroughly rinse the cleaning agent.)
i'm weary on what it would do if you were to heat it and
vape it, but it's not like you're burning and combusting it in the traditional
sense. if it works for you i'd keep on using it but definitely rinse your atomizer very thoroughly and watch out for a potential polycaf taste. that's a pretty awesome idea, and remember that a little goes a long way. it's readily dissolved in hot water, and rinses very clean with hot water.
but i'm guessing if you have access to the product you may already work with coffee? or are just an enthusiast. but that stuff is amazing. the only concern i would have is lingering polycaf hiding out in your wicks and some of the other parts of the atomizer where it's harder to give a good rinse.
i say try it again and let us all know! cuz if it works out well for you i would totally do it too. i don't think that it could be overwhelmingly harmful to you.
