Usage
What does sanitizer mean? Sanitizer is a substance or fluid designed to kill germs on skin and objects. To sanitize means to clean something by removing the dirt or destroying the germs on it. Food service operations use sanitizer to clean their equipment so that food doesn’t become contaminated with bacteria or other stuff that shouldn’t be in it. Sanitizer also refers to household products (especially hand sanitizer) that are used to prevent the spread of disease by killing germs on surfaces and skin. Example: We use industrial-grade sanitizer in the restaurant kitchen to keep our equipment free of germs.
Etymology
Origin of sanitizer
Explanation
Sanitizer is a product that's used to make something extremely clean. Using hand sanitizer is one good way to help keep germs from spreading. Sanitizer doesn't just clean, it sanitizes, or kills viruses and bacteria. Both words come from sanitary and its Latin root, sanitas, which means "health." If you're cleaning a kitchen or bathroom, you might want to use a sanitizer spray on germy surfaces, and when you can't wash your hands with soap and water, hand sanitizer is the way to go!
