I don't think electronics cleaner would have the same effect. It would evaporate too quickly and leave no residue whereas the spray on oil/lubricant ie. WD-40 leaves a residue. I think that a description of "why it works" would be that the oil left behind on the surface of the condenser would act as a heat sink thereby overcoming the problem of a hot condenser. My curiosity is even piqued a little bit by the idea of a slightly heavier oil working even better than WD-40... That'll have to be for someone else to try out though.
