Cleaning right: Don’t skip the first step

Published April 29, 2020

A professional cleaner offers a critical piece of cleaning advice: If you want to really clean a surface, it’s a two-step process.
  1. Use soap to break up the biofilms.
  2. Then disinfect.
That’s because dirty surfaces are coated in clusters of germs called biofilm that resist disinfectants. These germs have to be removed before a chemical can effectively kill off any lingering viruses or bacteria.
