A Sad Question/The BS+V Miracle

So I was in the Walmart cleaning products aisle a couple weeks ago and a very confused looking guy in his mid-to-late twenties approached me.

"Excuse me, can I ask you a question? ... How do you clean a bathroom?"

Ummm what?  I was super confused.

"Like... what kinds of things should I buy to clean it?  What should I use for scrubbing?"  He held up some sponges and a couple of bottles of Mr. Clean-like products.

"Uh, I don't know, looks like you're on the right track, is this for soap scum or what?"

"Yeah the thing is I've kind of left it a really long time and it's pretty bad..."

I told him to look for Magic Erasers (which he'd never heard of - DUDE, do you not watch TV at ALL?  Oh wait, they only advertise cleaning products during "girl" shows like Real Housewives.  THANK YOU sexism in marketing, you are the reason this young man is asking me such absurd questions) and went on my merry way.

Two thoughts on this:

1.  Why has a man who is approximately my age never cleaned a bathroom???  Has someone always cleaned up after him OR more gross, has he lived in the same place since he moved out of his parents' house and never cleaned it and by "pretty bad" he means How Clean Is Your House bad?

2.  A week or two later I realized the secret to easily cleaning soap scum from a shower/tub which I now wish I could have imparted on this lost little puppy:  baking soda and vinegar.  Before we moved out of our gross apartment I wanted to find a way to clean the oven without having to buy respiratory protection/oven cleaner and a quick Google search told me that I could basically just use baking soda and vinegar.  I wish I had before and after pictures because it worked AMAZINGLY well.  I figured if it worked on oven gunk it would likely work on simple soap scum (and I'd had experience soaking shower floors in vinegar to remove that awful dead skin/soap scum mixture that is the worst thing to clean in the world).  I made a baking soda and vinegar paste, painted it on the shower walls, waited for it to dry, and then everything wiped off like you see in commercials.

So the moral of the story:  PARENTS, please make sure you teach your kids how to clean things before they move out.  Also, baking soda and vinegar are literally the only cleaning products you need.  Stop wasting money on toxic garbage that doesn't even work in the first place and go spend 5 bucks (total) on a giant jug of vinegar and box of baking soda.
