Ontsmet

Ontsmet is a Dutch verb meaning to disinfect, sanitize, or decontaminate a surface, object, or body part in order to reduce or remove microorganisms. It is used in households, healthcare, food processing, and public health. The related noun ontsmetting refers to the process of disinfection.

In practice, ontsmetten involves cleaning to remove visible dirt and then applying an antimicrobial agent appropriate to the context. For non-porous surfaces, common chemical disinfectants include ethanol or isopropanol, sodium hypochlorite solutions, and hydrogen peroxide-based products. The intended effect depends on a specified contact or dwell time as stated on the product label; insufficient contact time can leave microbes active. Some agents are effective against bacteria and viruses but not spores; for spores, sterilization methods such as heat or specialized chemical sterilants may be required.

Proper use includes following safety guidelines: wear gloves, ensure adequate ventilation, and store chemicals away from children. Surfaces should be visibly clean before disinfection, since organic matter can reduce efficacy. In healthcare and food-service settings, ontsmetting is governed by national and international guidelines and product registrations to ensure safety and effectiveness.

Differences to sanitization and sterilization are commonly noted: sanitization reduces microbial load to safe levels, disinfection targets pathogens, and sterilization aims to eliminate all viable organisms. The term is also used in everyday language to describe routine cleaning and disinfection of hands, surfaces, or equipment.
