If by corruption, we speak of a thing "tainted by demonic energy", i believe there is some spells who can drive back corruption in certain cases, or at least stop/seal/slow down the corruption.

At least, we know that the corruption effect of apophis venom cannot be reversed unless it is treated quickly (Q&A). I'm not sure if it's  the same corruption but it certainly involve demonic energy.
