The Vehicle Carbon Cleaner is specifically designed to remove the internal carbon deposits of parts such as automobile engine blocks, spark plugs and fuel supply nozzles, which can help improve engine power, reduce vehicle exhaust and save fuel. Over time, a combustion engine builds up internal deposits, such as carbon, tars, gums, etc. While these are natural by-products of the combustion process, they can accumulate and affect the performance of an engine. It is simply removing components from the engine and cleaning them, either with solvents or by ‘blasting’. The Vehicle Carbon Cleaner is very effective and useful.
