  The information bleaching refers to any physical process that removes quantum
information from the initial state of the physical system. The no-hiding
theorem proves that if information is lost from the initial system, then it
cannot remain in the bipartite quantum correlation and must be found in the
remainder of the Hilbert space. We show that when hiding map acts on the input
state in the presence of indefinite causal order, then it is possible to hide
quantum information in the correlation. One may ask, does it then violate the
no-hiding theorem? We analyse this question and argue that in the extended
Hilbert space, it will still respect the no-hiding theorem. We also discuss how
to mask quantum information using superposition of two hiding maps. Our results
can have interesting implications in preserving the fidelity of information,
preservation of quantum coherence and work extraction in the presence of two
hiding maps with indefinite causal order. Furthermore, we apply the hiding maps
in the presence of indefinite causal order on half of an entangled pair and
show that entanglement cannot be preserved. Finally, we discuss that even
though quantum entanglement is destroyed, the entanglement fidelity under
indefinite causal order is non-zero and can approach close to one.
