Using high order modes (HOMs) for plasma ignition allows overcoming limitations imposed by weakly coupled fundamental modes. HOMs ignition can be applied to different SRF cavities making plasma processing potentially possible for any cavity geometry, including spoke resonators like the SSR1 for PIP-II. The results of plasma processing of LCLS-II HE cavities in vCM are presented, along with the summary of the plasma cleaning operations in the CM test cave. The preliminary results of plasma cleaning tests of SSR1 cavities and future plans are discussed.}}, }
