Car engine carbon cleaning is a service that removes sooty carbon deposits from your engine. These deposits build up over time and can clog various components.

There are a few different approaches to engine cleaning. The most basic one involves using chemicals to dissolve the sooty deposits; you can buy a fuel add-in treatment to use at home. In another technique, a mechanic injects super-refined gases or fuels into the fuel system. A more traditional method involves removing components from the engine and cleaning them by ‘blasting' or using solvents.
