What will cause iron to dissolve but not attck aluminum?

I have an engine make of cast aluminum and a steel bolt stuck in it. I drilled the bolt out but i cannot remove the shell with the threads. Is there something i can use to cause the steel bolt to rust/dissolve but not attack the aluminum block?

Yes. Dilute sulphuric acid will dissolve the iron (steel) but won't touch the aluminium.
