It efficiently dissolves and removes soot, carbon deposits from the area of diesel injectors, the exhaust gas in- and outlet systems and other zones subject to such contamination. Application: for easy disassembly of corroded injectors; cleaning the AGR and EGR valves (when they are disassembled); cleaning the turbocharger and inlet manifold (only when they are disassembled); cleaning other units of the diesel engines from carbon deposits.
