No, once they get dirty they need to be cleaned with a spray cleaner. It works nearly every time, unless they are so far gone that they can't be cleaned. Sometimes you can improve them just by working them back and forth, but the problem will return if you don't clean them properly.

This is a possiblity, but not likely. The scratchiness he describes is almost always from dirty volume controls (potentiometers (pots)).
