I suspect that Scalextric uses AC wallwarts because they sell their sets all over the world. They have a single power base and several transformers that are made for different line voltages and plug styles. If the contacts inside of the Lionel transformer are corroded lighter fluid would not clean them. Contact cleaner or fine sand paper, like 1500 grit, would be better. Any hardware store should sell volt meters.
