What does demineralize mean?
Demineralize means to remove minerals from something, or to lose mineral content, and it appears chiefly in two settings. The first is industrial and chemical: water that has been demineralized has had dissolved salts and minerals stripped out, making it suitable for laboratories, boilers, and manufacturing processes where pure water matters. The second is biological, and far more familiar to everyday life: teeth and bones can demineralize when acids dissolve their calcium and other minerals. Dentists warn that sugary, acidic foods and drinks allow bacteria to demineralize tooth enamel, weakening it and paving the way for cavities — though fluoride and saliva can reverse early damage through remineralization. The word derives from mineral, with the prefixes de- (removal) and -ize (to make or become), and its standard noun form is demineralization. It is a formal, technical term, rarely heard outside science, medicine, and engineering.
verbTo remove minerals from a substance, such as water or soil; in dentistry and physiology, to lose or cause the loss of mineral content, especially calcium, from bones or tooth enamel.
- To remove minerals from something, especially from water (as in industrial demineralized water).
- To undergo or cause the loss of natural mineral content from living tissue, such as bone or tooth enamel, as in demineralization caused by acid or disease.
"Prolonged exposure to acidic soft drinks can demineralize tooth enamel, leaving it vulnerable to decay."
"The laboratory uses a special resin to demineralize water before it enters the cooling system."
"Without adequate fluoride and saliva, plaque bacteria rapidly demineralize exposed areas of enamel."
Every time you sip something acidic, your teeth begin to demineralize — and every minute until your next meal, they quietly rebuild themselves.

Etymology of demineralize
Demineralize combines three elements: the prefix de- (from Latin, indicating removal or reversal), the root mineral (from Medieval Latin minerale, relating to ore or what is mined), and the suffix -ize (from Greek -izein, forming verbs meaning to make or treat). It emerged as a technical coinage alongside mineralize, which dates to around the late sixteenth century, with demineralize following once chemists needed a term for stripping minerals from substances. Its derivatives include demineralization and the adjective demineralized, both common in industrial and dental writing.

How demineralize is actually used
Demineralize is a technical term most common in scientific, medical, dental, and industrial contexts; it rarely appears in casual conversation. In dentistry it often carries an implied contrast with remineralize, since enamel constantly cycles between losing and regaining minerals.
Easily confused with demineralize
Demineralise is simply the British spelling of demineralize, not a different word.
Demineralization is the noun naming the process itself, while demineralize is the verb describing the act.
