That is because you used the wrong "electronic cleaner." A contact cleaner is for contacts, not for controls. For controls you need a chemical which cleans and lubricates. I use Caig DeoxIT F5 FaderLube. It is designed to clean and lubricate controls. After the cleaning part evaporates the lubricating part remains and keeps the control quiet. If FaderLube doesn't cure the problem the control is at fault and will have to be replaced.
