Some of us lacked fully formed adult brains when we were kids and so we sometimes did stupid shit that humans with more fully developed and advanced brains wouldn't. Also, times were different decades ago. There was a time when we didn't have things like dish detergent with peroxide or tide with oxy clean, so sometimes we'd just add a drop of detergent to some peroxide to help it penetrate into fabric and better remove a blood stain or things like that.

That aside, "cleaning better" is hardly the only rationale for why I'll sometimes whip together a DIY cleaning product. I'm guessing I'm not alone in that. So I think focusing on that one rationale might be missing the bigger picture for peoples' motivations.
