In the cleaning industry, words like “sanitise” and “disinfect” are often used interchangeably on bottle labels. However, from a hygiene and public health perspective, these two terms represent distinct cleaning processes with different chemical strengths and goals. Understanding the difference helps you maintain a healthy home environment.
Sanitising: Reducing Bacteria to Safe Levels
Sanitising is a milder process designed to reduce the number of bacteria on surfaces to safe levels (usually by 99.9%). It is commonly used on food-preparation surfaces, dining tables, and children’s toys. Common sanitising products include diluted dish soap, light vinegar sprays, or kitchen counter sprays.
Disinfecting: Killing All Germs
Disinfecting is a stronger chemical process that kills bacteria, viruses, and fungi on contact. It doesn’t necessarily clean dirty surfaces, but it eradicates the pathogens remaining on them. Disinfecting is crucial for high-touch areas like toilets, taps, door handles, and hospital equipment. Disinfectants include bleach solutions or commercial sanitising sprays containing active alcohols or quaternary ammonium compounds.
The Clean-First Rule
You cannot disinfect a dirty surface. Dirt and organic oils act as a shield, preventing disinfectants from reaching the germs underneath. Always wash the surface with soapy water first, wipe clean, then apply your disinfectant spray and let it air-dry to kill remaining germs.
