In a method for cleaning exhaust gases containing nitrous gases, the exhaust gas is passed through a scrubbing solution that contains a reducing component with which the nitrous gases are reduced to nitrogen wherein as the reducing component ammonium ions (NH4+) are used. The scrubbing solution comprises water and ammonium sulfate ((NH4)2SO4). Alternatively, the reducing component is ammonia gas.
