Isn’t it water that basically turned to vapor and then back? That should get rid of most minerals.

So the top part, the “heatsink” part, I can grab it by that, but the grip is bad and I can’t take it out (at least not without rapidly grabbing it and pulling it to the side out of the socket), and I don’t want to touch those electronics under it (as shown in your picture).

I can’t really grab it by the sides with fingers, I could perhaps with tweezers, but too afraid those could scratch something in the process.

A small suction cup might work as someone else mentioned though, but don’t have that.
