If Population II main-sequence stars have winds similar to the solar wind, then these stars could provide a feasible mechanism for expelling red-giant ejecta from globular clusters. For clusters having line-of-sight velocity dispersions less than 22 km.s^–1, the mass and energy output of main-sequence star winds is found to be sufficient to establish a cluster outflow which is capable of removing all red-giant ejecta. This mechanism provides a natural means for continuously sweeping all or most globular clusters of stellar ejecta.
