Since I am not Latin-literate, I'll have to rely on tools from here. Google translate takes this and returns, literally, "Wash the dirt". Not nearly as dramatic, so I doubt that's the intended meaning.

In the context of the scene, this can probably be more liberally interpreted as "Cleanse this filth!", which sounds a lot more like what a modern-day paladin might say.

@chepner has contributed in comment that this is also a line from a Latin Catholic hymn Veni Sancte Spiritus, which is presented in several different translations, but seems to be commonly used as "Clean what is unclean," and given Michael's background something very likely for him to use.

In the print version, Michael says "Lava quod est sordium!" when casting off the swarm attacking Harry. Michael actually used this phrase at several points in the series, either as a battle cry or when invoking the power of his faith.
