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.
