degreaser
dee-GREE-ser
/diːˈɡriːsər/
A powerful chemical cleaning agent designed to break down and dissolve water-insoluble grease, oils, resins, and road tar.
Degreasers are highly alkaline or solvent-based cleaners used on engines, wheels, and door jambs, but they are too harsh for regular paintwork as they strip wax and can dull the finish.
The story behind the word. The word degreaser combines the Latin prefix 'de-' (meaning 'off' or 'away') with 'grease', which comes from the Latin 'crassus' (meaning fat). Historically used in wool processing to strip natural lanolin from sheep's wool, degreasers became vital in the automotive era to clean the heavy petroleum lubricants used in internal combustion engines.

- solvent: A solvent dissolves substances, while a degreaser specifically targets lipids, fats, and heavy oils.

Memory hook
A 'de-greaser' takes the 'grease' away. Degreaser cuts through engine oil and grease.
When not to use
Do not use as a general car wash soap; it will strip all protective coatings and dry out plastic trim.
Fun facts
- Many modern automotive degreasers use d-Limonene, a natural solvent extracted from citrus peels, which cuts grease effectively and smells like oranges.
- Using a degreaser on hot engine parts can cause the chemical to dry instantly, leaving permanent white stains on aluminum components.
