My laptop's volume knob has been "scratchy" for some time. I have read on The Internets that Deoxit is a good solution for this problem.
Usually, it is advised to take the device apart to apply it, but i don't want to do it, because my laptop is otherwise perfectly fine.
Question: Can i just apply some Deoxit as-is, without taking it apart? will it cause any damage? is the residue a problem?
