I find the soap, glycerine and vinegar treatment video interesting but, after using a few brushes over forty years, I've never had to clean one other than with a daily 20-30 second post-shave routine. I flush out soap with fresh water in the shaving cup (cleans the cup, too), rinse, sling the brush over the sink, towel-dry/fluff the bristles and leave it hanging bristles down.
