  We discuss conserved currents constructed from the Cotton tensor and
(conformal) Killing-Yano tensors (KYTs). We consider the corresponding charges
generally and then exemplify with the four-dimensional Pleba\'nski-Demia\'nski
metric where they are proportional to the sum of the squares of the electric
and the magnetic charges. As part of the derivation, we also find the two
conformal Killing-Yano tensors of the Pleba\'nski-Demia\'nski metric in the
recently introduced coordinates of Podolsky and Vratny. The construction of
asymptotic charges for the Cotton current is elucidated and compared to the
three-dimensional construction in Topologically Massive Gravity. For the
three-dimensional case, we also give a conformal superspace multiplet that
contains the Cotton current in the bosonic sector. In a mathematical section,
we derive potentials for the currents, find identities for conformal KYTs and
for KYTs in torsionful backgrounds.
