Coil seems to rust or corrode easily? Taste bad fast

[Phone Guy]

I rewick pretty often, every tank or every other tank. My favorite juice (diy) seems to gunk up Coils quickly. So I dry burn and rewick.

After a few tanks the Coils look rusted or badly corroded. And it seems that when they are badly rusted or corroded (or whatever it is) after dry burning they seem to either taste bad and/or get gunked up much more quickly, after just a ml or two (half a 4.5-5.0ml tank at most)

I use 28gauge kanthal a1 most of the time.

I wonder if your juice contains distilled water, causing the corrosion. The coils should last way longer than just a few tanks. Another possibility is the wire's quality. I'm buying directly from Temco, fast and cheap shipping. Never had an issue as you described.

Not that I add. It's DIY juice mostly... The wire is from lightning Vapes, kanthal a1...?

Lightning Vapes sells good wire. I wouldn't be concerned about the metallurgical quality of their Kanthal. I see a similar problem with my RDA occasionally. It actually clears off with a good dry burn (no wicks) and quenching the coils in cold water. They sometimes develop a reddish buildup, depending on the juice I'm using. It resembles rust, but comes off with heating and quenching. Doesn't mean that there's anything wrong with your juice recipes. Different ingredients just do that once in a while.
Try heating and quenching, and see if it doesn't remove the discoloration. If not, and the coils are actually rusting, it may be time to find a new supplier for your ingredients. That could be a sign that they are diluting things with water. Which is obviously not something you want.
Also, what are you wicking with? Using improper types of cotton could leave bleaching chemicals on the coils, which would definitely corrode them. And maybe your lungs too.

And you are basing this info on what? Which type of bleach causes this corrosion?

Switch to n80 it won't rush kanthal has iron in it that's why it rusts

The dioxins used in commercial textile processing, chlorine, that sort of stuff.

What flavoring are you using? I use a fair number of coil gunker flavors. I've been using LV kanthal for quite some time with no issues. I usually quench or brush along with dry burning though.
