In the UK, the word "Swarfega" may be used as a generic term for all similar cleaners, particularly if they have the same green jelly-like appearance as genuine Swarfega. According to the company website, the name derives from "swarf", a Derbyshire word for oil and grease, and "ega", as in "eager to clean".[4] "Swarf" now commonly refers to the metal shavings and chips resulting from metalworking operations.
