## Definition

a liquid or spray used to kill germs and bacteria on surfaces. You use it to clean floors, counters, or your hands to keep them safe from illness.

For teachers: a substance used to destroy or inhibit the growth of microorganisms on inanimate surfaces. Often distinguished from antiseptics, which are applied to living tissue.

## Examples

- Wipe the kitchen counter with a disinfectant after cooking.
- The hospital staff uses a strong disinfectant to clean the floors and equipment after every patient visit.
- While a mild soap removes dirt and some bacteria, a hospital-grade disinfectant is required to ensure the complete eradication of pathogens from high-touch surfaces.
