But if that were the issue, why would it only do this after it hasn't been in use for months? D:

This makes sense. I sort of had the feeling it was something in the sticks themselves. It gets really hot in my room at home, and in my dorm I keep it right by my window. Maybe since I haven't been using them it just collects rather than getting wiped off by my thumbs?
