Belt dressing if the belt is in good condition. Make sure that it is not a pulley squeaking and if the belt is in bad shape replace it.
Never use belt dressing on a serpentine belt. Clean the dressing off and recheck the pulleys.
Clean all of the dressing back off and replace the belt.
Belt dressing is the worse thing you could do. Remove the belt and clean all of the pulleys and install a new belt.
Horrible idea. If the engine is an Interferance engine and the belt breaks, serious engine damage will occur. If not you will be stranded when the belt breaks and pay a towing fee. Replace the belt at the scheduled mileage and forget belt dressing. If the belt is worn out, no amount of dressing will fix it.
