Kevin,

The relay may be sticking because of residual magnetism. A piece of paper between the relay poles, i.e the coil centre and the armature, will prove this - if it's residual magnetism, the relay will drop out fine once you increase the magnetic reluctance. If that's the case, a bit of Scotch or even PVC tape should provide a cure. Reversing the leads to the relay will also help for a time, although if there's a diode across the relay coil, that will need reversing too.

Some relays provide a copper stud to keep a small air gap: others even have an adjustment screw for the same purpose.
