Tec4 AdBlue Cleaner is an advanced additive treatment specially formulated to prevent and dissolve harmful crystallization inside SCR (Selective Catalytic Reduction) exhaust systems. Diesel exhaust fluid (DEF/AdBlue) can easily crystallize at low operating temperatures, causing severe blockages in dosing injectors, pumps, supply lines, and catalytic converters.

Engineered with active anti-crystallization chemistry, Tec4 AdBlue Cleaner breaks down urea deposits, maintains fluid atomization, and prevents costly SCR component failure, keeping modern diesel emission systems clean and fully operational.

Key Performance Benefits

• Prevents & Dissolves Crystallization: Inhibits the formation of white urea crystals and dissolves existing deposits inside the SCR system.
• Keeps AdBlue Injectors Clear: Maintains precise fluid atomization from dosing injectors to ensure complete NOx reduction and optimal exhaust mixing.
• Protects SCR Pumps & Tank Units: Prevents crusting and sediment buildup around heating elements, level sensors, and internal fluid lines.
• Prevents System Fault Codes: Helps avoid expensive dashboard error lights (AdBlue fault warnings) and emergency engine non-start countdowns.
• Optimizes Low-Temperature Performance: Ensures consistent fluid delivery and dispersion during short journeys and low ambient temperature driving.
• Extends SCR System Lifespan: Protects high-cost exhaust components against premature clogging, reducing downtime and expensive workshop repairs.
