Do you dry burn your coils?

[raffles]

I accidentally stumbled upon this article recently by Farsalinos http://www.ecigarette-research.org/research/index.php/research/research-2015/212-db

Essentially dry burning your coils increases the amount of metal you inhale, but is it to a significant enough degree to be concerned, seeing as some level of metals are detected anyway?

Do any of you guys just wash/soak your coils, and does it do as good a job at cleaning the gunk off?

Dry burn, then rinse under tap to get rid of residue.

i also dry burn and rinse.
We all have to make our own risk assessments on these things.
If you wanted to absolutely minimize all risk you would not do it,

In Farsalinos' artice, he explains that the risk is likely to be small, but since the risk is avoided by rebuilding, he recommends not taking the risk. Specifically:

"How much is metal exposure elevated by dry-burning the coils? Probably not very much. That is why we think the vapers have over-reacted to my statement on RY4radio. However, we do not see a reason why the exposure to metals should be elevated by doing something which can be avoided."

I do dry burn, but only to just glowing. If the coil is too manky, I rebuild rather than doing an aggressive dry burn. I mainly use NiFe wires (for TC) though, and they can't handle as high temperatures as Kanthal.

Burn and rinse for me,

Feels like I'm discussing some weird hairdresser

dry burn and rinse and always been ok

I ultrasonic bath used coils first which helps get rid of extra crap and exactly like @danb, I don't glow to the point of lightning up the room . I pulse to a low cherry red to cremate the gunk and back in the ultrasonic bath again and a good rinse and they come up lovely and clean . I don't aggressively dry burn either, if there's stubborn gunk on a clapton or twisted coil, I bin them.

Invariably, a dry burn is needed when installing coils to test they're firing properly and to pinch up contact coils if required, same applies though, only pulse to a low cherry red to adjust and test. A dry burn is a dry burn, whether done at installation or to clean and reuse coils.

Done carefully and with common sense I'm happy to do it myself as well from various articles I've read on both sides of the argument as to whether to do it or not . Obviously dry burning materials like Ni200 isn't particularly recommended, I dry burn SS and Ni80.

@danb, NiFe is perfectly OK to very carefully dry burn is it please mate? More specifically 48 or 52? Still haven't had a chance to build with the stuff I have sat here, info like that is handy to have upfront though for when I can get building .

I have been cautiously dry burning NiFe48 (Zivipf) for ages now and it seems fine to me. If you overdo it, the wire will degrade - I once hammered a particularly filthy coil at 40W, which went up to a pale yellow, and the coil snapped in the centre. I haven't done more detailed experiments...

Usually by about the 3rd re-wick, I rebuild the coil.

I don't heat any TC coils at all at installation, except for SS, and at rewicking I tend to just do one pulse at 600F to clean them off a bit as suggested by @danb. I do dry burn SS at rewicks and pretty aggressively at that, but I don't think it's a great idea, just one born out of laziness.

I do dry burn mine. Just a couple of times I don't keep them for Months like some. You can rewick and replace coils for about 20p it's just not worth keeping them for months on end. Tc coils I just clean. There's a risk in everything we do, I probably inhaled more metal while being a welder than I ever will vaping
