DPF Soak

Tec4 D.P.F Soak and Tec4 D.P.F Flush are professionally developed cleaning products that work together to effectively remove soot, carbon, and ash deposits from diesel particulate filters (DPF). This combination restores exhaust gas flow, improves DPF efficiency, and helps maintain optimal engine performance and reduced emissions.

The products are compatible with all types of DPF systems and are capable of dissolving not only soot and carbon, but also stubborn oil-ash deposits that often cause regeneration failures.
Application is only permitted using the Tec4 Carbon Cleaning Machine, ensuring a safe, controlled, and effective cleaning process.

Our Tec4 distributors are happy to assist professional workshops with the correct use of this system.
