Cleaned surfaces may be germ-free, but they’re not bare
Since the outbreak of COVID-19, surfaces in public spaces are cleaned more often. While disinfectant solutions eliminate germs, they don’t leave behind a truly bare surface. They deposit a thin film that doesn’t get wiped up, even after giving the surface a good polish. In a new study, researchers show that residues left by commercial cleaning products contain a wider range of compounds that could impact indoor air quality than previously thought.
