What must be done to surfaces before sanitizing them?

Before sanitizing surfaces, it is essential that they are cleaned. This step is critical because sanitizing is an effective means of reducing pathogens on surfaces, but it works best when the surfaces are free from food residues, dirt, and other contaminants. Cleaning removes these materials, allowing the sanitizer to adhere properly and be effective in killing remaining bacteria and viruses. If surfaces are not cleaned first, the presence of grime and debris can create a barrier that inhibits the disinfectant's action, potentially leaving harmful microorganisms behind.

Proper cleaning typically involves using soap and water and effectively scrubbing the surface to remove any visible soil or pollutants. After cleaning, surfaces can be sanitized to further ensure they are safe for food contact and reduce the risk of foodborne illness.
