You can try flushing the movement with a petroleum solvent like paint thinner or cigarette lighter fluid to remove the wax. The solvent should dissolve the wax without leaving any residue. WD40 will also work, but may leave an oily coating.
In any case, using any of the above should make an improvement in freeing up the motion of the vane.
