Swarfega (/swɔːrˈfiːɡə/) is a brand of heavy-duty hand cleaner made by Deb Limited, a British company based in Denby, Derbyshire. It is used in engineering, construction, and other manual trades, such as printing.

It is a gelatinous, thixotropic substance, dark green or orange in colour, which is used to clean grease, oil, printer's ink, or general persistent, hydrophobic dirt from the skin. Swarfega works a small amount into dry skin and then wipes or rinses off. As with other such cleaners, it can be more effective than soap or other common cleansing products at removing such dirt; accordingly, Swarfega has become virtually ubiquitous in environments where this kind of dirt is common, such as garages and machine shops.
