All I know is, I *don't* want to know.

Why does the Target brand spray-and-leave-on shower cleaner work so much better than the stuff that is twice or three times as much?

And more eerily, why does the $1.99 XCEL brand (Walgreen's) drain unclogger stuff work amazingly well, when the $5.99 Liquid Plumr or Drano don't work worth a lump of coal?

I refuse to look at ingredients. Or country of origin/production.
