What does sanitisation mean?
Sanitisation is the process of making something clean and safe by removing or reducing harmful microorganisms. It is especially common in food production, healthcare, hospitality, waste management, and household hygiene. Sanitising a work surface, for example, treats it with a process intended to reduce the number of harmful organisms, whereas sterilisation aims to eliminate all viable microorganisms. The word can also be used more generally for making an object or environment suitable for a particular purpose. In figurative contexts, especially political and editorial discussion, sanitisation refers to removing or softening material considered sensitive, controversial, or inappropriate. Although broadly associated with hygiene, the term should not imply that a sanitised object is necessarily sterile. British English uses the spelling sanitisation; US English generally uses sanitization.

Sanitisation is hygiene in action: the deliberate process of making a surface or object safe from harmful microbes.

Where does sanitisation come from?
Sanitisation was formed in the 19th century from the verb sanitise, which in turn derives from the adjective sanitary. Sanitary comes from Latin sanitas, meaning health or soundness, ultimately associated with the Latin adjective sanus, meaning healthy or sound. Related English forms include sanitation, sanitary, and sanitiser, while cognates occur in several other European languages.

How sanitisation is actually used
In British English, sanitisation is the standard spelling, while the corresponding US spelling is sanitization. In food and public-health contexts, the term usually means reducing microorganisms to a safe level rather than eliminating every microorganism; in metaphorical use, it can suggest excessive removal of controversy or difficult material.
Easily confused with sanitisation
Sanitisation reduces or removes harmful microorganisms to a level considered safe, whereas sterilisation eliminates all viable microorganisms.
Cleaning generally removes dirt and matter, while sanitisation specifically treats a surface or object to make it hygienically safe.
