Yeah, my findings have been keep the bleach AWAY from anything wool/more vintage. 70s synthetic on forward you're good, though I wouldn't submerge. Mask it off where needed and spray, let sit, then hose off
Oh...AND...for some reason your spots/staining might come back over time. You're not eliminating them, just whitening them. Know that...and also remember that you can only do this a few times before making the pennant brittle
