Plastic on Wacom Grip Pen Became Sticky and Gunked Up
I have no idea how this happened, but seemingly overnight the rear half of my Wacom grip pen got super sticky. It felt like the same kind of residue left behind when you unsuccessfully peel a sticker off something. I did not spill anything on it or use it with dirty hands. It was (and I guess still is) so puzzling to me. First thought was to get this grossness washed off. But surprisingly the same cleaning stuff I'd normally use to get the sticker residue off of something didn't work on the grip pen. In fact, the cloth I was using to clean it just made it worse by gunking it up with little fibers. Ugggghh.
After searching online for an answer I came across a couple other people with the same problem. There's speculation on humidity, oil from your fingers, and some kind of plastic decomposition. I don't know. Strange stuff. But I did find the solution to getting it removed: 70% isopropyl alcohol. As you can see from the image below, cleaning with the alcohol takes off this gunk in little black flakes. Even with a cleaner that finally worked, it took a decent amount of scrubbing for it to be fully removed. And it makes a mess.
I'm sure this post might not be of use to many since this seems like a rare occurrence, but maybe it'll stick in the back of your head if you ever run into the same troubling issue I did. Sure beats spending $65 on a new grip pen. Does anyone have any idea what caused this in the first place? Or why it was the isopropyl alcohol that did the trick but not other stickiness cleaners?
