Word Origin and History for cleaner
mid-15c., agent noun from clean (v.). Meaning "shop that cleans clothes" is from 1873. To take (someone) to the cleaners "get all of (someone's) money" is from 1921.
Old English clæne "free from dirt or filth; pure, chaste, innocent; open, in the open," of beasts, "ritually safe to eat," from West Germanic *klainoz "clear, pure" (cf. Old Saxon kleni "dainty, delicate," Old Frisian klene "small," Old High German kleini "delicate, fine, small," German klein "small;" English preserves the original Germanic sense), from PIE root *gel- "bright, gleaming" (cf. Greek glene "eyeball," Old Irish gel "bright").
"Largely replaced by clear, pure in the higher senses" [Weekley], but as a verb (mid-15c.) it has largely usurped what once belonged to cleanse. Meaning "whole, entire" is from c.1300 (clean sweep in the figurative sense is from 1821). Sense of "innocent" is from c.1300; that of "not lewd" is from 1867; that of "not carrying anything forbidden" is from 1938; that of "free of drug addiction" is from 1950s. To come clean "confess" is from 1919, American English.
mid-15c., "make clean," from clean (adj.). Related: Cleaned; cleaning. From clean out "clean by emptying" comes sense of "to leave bare" (1844); cleaned-out "left penniless by losses" is from 1812.
Old English clæne "dirtlessly," also "clearly, fully, entirely;" see clean (adj.). Cf. similar use of German rein "clean."
