How can I revive my cast iron skillets? - how to get wax off of new cast iron skillet

I have a collection of cast iron pans, which I have never used, because I tried to destroy in order to melt the wax to put on them before selling them. Follow the instructions to melt in the oven and pushed off. Then I tried to wash it all and did not. Now, say unnecessarily, they have done and rusty in places that are in poor condition, but I need to know if there is a way to fix this problem?
