What does blanco mean?
Blanco is a noun denoting a white — sometimes khaki or green — preparation applied to fabric, canvas, and leather to whiten or colour it. Its fame rests almost entirely on its role in military life: throughout much of the twentieth century, soldiers in Britain and the Commonwealth used blanco to keep their webbing belts, gaiters, and equipment pouches looking immaculate for parades and inspections. Sold in blocks or tins, it was mixed with water and brushed on, then polished once dry. The word entered English from Spanish, where blanco simply means 'white', and it shares a distant Germanic ancestor with everyday words like 'blank' and 'blanch'. Though household and military use of blanco has all but vanished, the word survives in dictionaries, veterans' memoirs, and collectors' circles as a small but vivid relic of service life.

Etymology of blanco
English borrowed 'blanco' directly from Spanish, in which 'blanco' means 'white'; the Spanish word itself descends from a Germanic source (*blank-, 'shining white') that also gave English 'blank', 'blanch', and 'blancmange' via French. The borrowing occurred in the context of trade and military supplies, and the word became established in British English during the era when blanco was standard kit for soldiers.
How blanco is actually used
Chiefly British and strongly associated with mid-20th-century military life; largely obsolete since synthetic webbing and modern cleaning methods replaced it.
