cleaning-chemicals industry takes on the final frontier…

…invisible stains. Finally, there are cleaners on the market that can clean up stains that are undetectable by any of the human senses.

Have you seen that commercial for a toilet-bowl cleaner? They say, “Bleach only hides stains.” Then they pour some purple stuff on the ceramic to reveal the hidden “stains.”

Um, what? Isn’t hiding a stain mean you get rid of the stain? By definition? I think it’s nuts that the cleaning-chemicals industry is inventing the problem of invisible stains. I have a solution to this problem: don’t pour that purple stuff in your toilet!

And then there are those “chemical residues” that watch you shower. The invisible, undetectable residues. How do we know that invisible residues are there at all? The TV tells us that they are there, of course. But wait, how do we know that the alternative cleaner doesn’t leave an invisible residue?

All this reminds me of the Emperor’s New Clothes. Or, more aptly, that old joke about the elephant repellant (“You don’t see any elephants around here do you? It must be working, then!”) People need to ignore these silly commercials and relax a little bit about cleaning. Just scrub the toilet bowl every week or two with a brush, then wipe the seat etc. with diluted bleach and be done with it! Jeez!
