So.... I have other idea.

We just make some disease (Virus or Bacteria) That consume all demonic energy. (For virus, that could modify cell that infected by Demonic Energy.) Then we inject in. The disease can replicate themselves.

Or if Demonic Energy is Virus (That's one of Assumptions, since it can modify DNA) just make specific cure or inject the modified immunity (Since nowadays there's no cure for virus)
