Kill More Germs by Cleaning… Less?

There’s clean, and then there’s CLEAN. Even if something looks clean, it might still be harboring microbes – many of them harmless, some of them definitely not. With most of the ways that we clean and disinfect — that is, kill germs — the clean doesn’t last as long as you might think.

Disinfectants work by attacking bacterial membranes and viral protein coats, breaking them down so that those germs fall apart and die. But the germaphobes were always right: As soon as a disinfectant dries, and a surface is re-exposed, like if someone touches or (worse) sneezes on it, it needs be disinfected all over again.

The next generation of cleaning products, however, add a trick: they lay down an incredibly thin polymer layer that keeps the germ-killing ingredients in place and effective for 24 hours at a time.

Ingenious is a new web series from the American Chemical Society about how leading-edge chemistry is taking on the world’s most urgent issues to advance everyone’s quality of life and secure our shared future.

Hosted by Alex Dainis, Ingenious spotlights stories from the front lines of chemistry research and development, where passionate innovators are stepping up to confront problems like pollution, overfishing, sustainability, and personal safety.

Ingenious releases every month.

Ingenious is made with funding and featuring scientists from 3M, Ascend Performance Materials, Baker Hughes, BASF, Dow, DuPont, Procter & Gamble, PPG, Royal DSM, SABIC, Solvay, and W. L. Gore & Associates, none of whom influenced any editorial decisions.
