There are little black specks of mold on LO's bathing suit - she has only worn it once! I have tried soaking in vinegar, washing with vinegar, washing with OxiClean, washing with a mixture of vinegar & OxiClean... should I give up??? I was thinking of trying non-chlorine bleach, but is it much different than OxiClean? Am I crazy to think about putting it in boiling water...?
