This spell is identical to transmute water to acid but it changes an equal volume of corrosive acid into plain, clear (and safe) water. A creature constructed of acid or native to the Quasi-Plane of Acid can be targeted by this spell and takes 1d4 points of damage per caster level (maximum 10d4). The elemental can attempt a Fortitude save to reduce the damage by half unless otherwise stated.
