The testing of various chemicals has yielded new chemicals and chemical mixtures for the use of removing carbon deposits from the internal combustion engine. Some of these chemicals and chemical mixtures have proven to work better across many different carbon types than other chemicals that were tested. These chemical terpenes are typically produced from plants. One standard terpene mixture is known as turpentine. The chemical turpentine and chemicals found in turpentine have been determined, through our research and testing, to be extremely effective at removing the carbon that is produced within the internal combustion engine.
