What does deodorising mean?
"Deodorising" is the British English spelling of "deodorizing", referring to the act of removing or neutralising unpleasant odours from people, places, objects, or substances. It is the present participle and gerund of the verb "deodorise", itself formed from the noun "odour" with the prefix "de-", indicating removal. The word appears most often in practical contexts: households deodorise carpets, refrigerators, and shoes; commercial cleaners deodorise hotel rooms and vehicles; and industry deodorises materials such as paper or rubber where unwanted smells would be undesirable. Products marketed as deodorising agents typically work by absorbing odour molecules, chemically neutralising them, or masking them with fragrance. The term is neutral in tone and widely understood, appearing in everything from advertising to technical manuals. While closely associated with personal care through its cousin "deodorant", "deodorising" applies far more broadly to environments and materials than to bodies alone.

Etymology of deodorising
The verb "deodorise" was formed in the 19th century by combining the prefix "de-" (indicating removal) with "odour", which derives from the Latin "odor" meaning smell. The same Latin root underlies related English words such as "odorless" (or "odourless"), "malodorous", and "aromatic" via Greek and Latin derivatives. The -is- spelling reflects standard British verb formation, while American English regularises it to "deodorize".
