may help but, be aware that the "caramel" may actually be the material from which the plug is made, breaking down.
Rubber and some plastics will do that.

So i got this USB Drawing Tablet that i keep in my bag. Well somehow the plug itself got some sort of sticky substance on it and inside it. It looks like it might be caramel. No idea how.
How would I go about cleaning it?
Thanks!
