The "Shelf-Life Deception" — The Dirty Secret Behind Every Bottle Under Your Sink
Turns out, I was scrubbing because my cleaner was already dead.
According to recent research from industrial cleaning labs, most commercial degreasers suffer from what chemists call "oxidative decay." The active ingredients — the molecules designed to break down grease — begin degrading the moment they're bottled.
By the time you buy that spray at the grocery store, it's been sitting in warehouses and on shelves for months. The chemical reaction that's supposed to dissolve grease? It already happened.
You're left with chemically "stale" liquid that forces you to provide the cleaning power through pure elbow grease.
