WD-40 is not a lubricant. It is a penetrating oil, originally designed to wash down metal decks and fittings on Navy ships and then be followed with a water sealant. The name stands for "water displacement formulation #40". It reacts badly with many plastics by leaching volatiles out and is hygroscopic .. if left in place on the surface of bare metals, it allows water to be held in suspension and promotes corrosion.
You need to flush it out of the clamp and displace it with a light lubricant that is kind to plastics, typically a spray on silicon- based lubricant will do well.
