1. First IPA ultrasonice bath then rinse with water then water ultrasonic bath and then I dried it.A few questions if I may?
How did you clean it when you first received it?
What did you use in it, have you used that in another vape?
How did you use it - flame or IH, and how did you apply them?
How was the taste and smell when you used it?
2. Self Grown yes I have used it many times before in my pax mini.
3. IH I used the adapter and followed the instructions on madheaters website then I promptly reduced the temperature setting to 250 C.
4. Taste and smell was well amazing (didn't notice anything different)
I also showed it to a friend that used to work in the metal industry he said it might be some residue from the machining that corroded (he used german terms I didn't really undertstand and can't really translate) and that I should just try to clean it out as good as I can (Q-Tip and IPA) and it shouldn't return (as long it's pure titanium).
