If I were to guess why it's not a thing that's readily taught I would assume it's because of the rather shockingly large lead lobby that exists in the USA pushing against education and regulation against lead. There's a meaningful establishment bent on making sure we don't ask about it or learn about it.

I am not sure it's quite so sinister.

I was today years old when I read the box of ammunition to see that it says "hey wash your hands" though I would assume we are talking about something more than soap and water.

How many cleaners that your parents taught you to use have you stopped and read the ACTUAL directions for? Like of course I know how to use Windex! Oh I shouldn't use it on electronics I guess even though parents always wiped down the TV with it.
