Anyone got tips for cleaning dirty knobs and switches? I've a Kenwood KA 3700 and the volume and source controls are playing up.
First step would be take knobs off if possible (I just mean pull them off the shaft, so you can get better access. Sometimes a grub screw needs undoing) and squirt in some Servisol.
