Wager DPF-Cleaner is a combination of detergents and active ingredients that reduce soot decomposition temperatures. Lower decomposition temperatures allow soot to be efficiently burned during combustion at a low exhaust gas temperature during normal driving (e.g. short tracks, stop-and-go). Regular use ensures efficient combustion and keeps the injectors and particulate filters clean. Regeneration of a clogged DPF filter is possible during operation and use.
