A quick video on cleaning electronic controls, especially switches and potentiometers (variable resistors). Note that it is possible for potentiometers and switches to wear out, although this takes a very long time or a lot of hard use before it happens. Getting the cover off and getting into the controls is probably the hardest part of this whole process.
This video is not likely to be helpful if you have a device that uses microswitches to adjust functions. These little switches can wear out and usually have to be replaced, although they can be cleaned if you are very careful when opening them.
