Besides razing the town to the ground or applying copious amounts of fire to the tainted area?

Doubt it, capable mages may be able clean up taint in small sources (which were not demonic to start with), or some humans, provided that the exposition was relatively brief/did not already turn then into mamono/incubus.

But mages are already rare, and if sweeping helped, there would be not so many troubles with the demon realms expanding.
