  We suggest a generalized method for elimination of spurious admixtures (SA)
from intrinsic nuclear excitations described within the
Quasiparticle-Random-Phase-Approximation (QRPA). Various kinds of
SA-corrections are treated at the same theoretical ground. The known
corrections are well reproduced. As relevant cases, we consider subtraction of
SA related with i) violation of the translational invariance (isovector E1 and
isoscalar toroidal and compression E1 modes), ii) pairing-induced
non-conservation of the particle number (E2(K=0) and E0 modes), and iii)
rotational invariance (E2(K=1) and M1(K=1) modes). The SA subtraction can be
done at the level of QRPA states, electromagnetic responses, and even
transition operators. The additional deformation-induced corrections are
proposed. The accuracy of the method is demonstrated by Skyrme QRPA
calculations for axially-deformed $^{154}$Sm.
