Before you beginRead every product label, gather only the tools needed, protect nearby food and electronics, and plan where wet items will dry.

Cleaning removes soil

Soap or detergent and physical action remove dirt, grease, and many germs from surfaces. In most ordinary household situations, routine cleaning is the main task.

A sanitizer or disinfectant must be used for the surface and purpose listed on its label. Contact time, dilution, ventilation, and pre-cleaning requirements matter.
