Hi hrry
I don’t think this issue is from usage. My neckband was in storage for a few days, and when I took it out, I noticed this greasy substance on it. I cleaned it with a damp cloth, but it came back after a few weeks. I even tried using isopropyl alcohol, but the problem returned again.
After doing some Googling, I came across the term “plasticizer leak”, and searching that (“plasticizer leak from the neckband material”) even brought me to this Nothing Community thread. So here I am!
If anyone knows a proper fix, please share it. This stuff is really gross!
Thanks!
