By breaking down and flushing those deposits, the formula helps recover normal SCR performance and can reduce issues like restricted DEF flow or reduced engine responsiveness when the emissions system is impaired. It is sold as a 6-pack of single-use bottles and is intended for addition only to the DEF\/AdBlue reservoir—never the diesel fuel tank.\u003c\/p\u003e\n\n\u003ch3\u003eHow does it clean stubborn white deposits in the SCR system?\u003c\/h3\u003e\n\u003cp\u003eThe Rislone formula contains surfactant detergents and urea-compatible cleaning agents that dissolve crystallized residues without harming DEF components.
