1-Box Diesel Cleaning

Professional 1‑Box Cleaning for Cleaner, More Efficient Diesel Performance

When your diesel vehicle shows signs of restriction or reduced emissions performance, professional 1‑Box cleaning from DPF Clean Technologies Inc can restore proper flow and efficiency. Our service targets soot, ash, crystallized DEF deposits, and other contaminants that accumulate inside the DOC, DPF, and SCR components housed within the 1‑box assembly. Contact us today.

Complete 1‑Box Cleaning, Testing & Structural Restoration

Our high‑capacity ovens allow us to bake the entire 1‑box assembly, the most effective method for deep cleaning DOCs and SCRs. After baking, we perform a full pneumatic blowout to remove ash and hardened deposits.

To ensure the unit is structurally sound, we also perform:

• Pressure testing to identify cracks, leaks, or internal failures
• Welding and fabrication repairs for damaged shells, seams, or mounting points
• Flow testing to verify restored airflow and proper restriction levels

Every cleaned 1‑box is returned fully inspected, tested, and ready for installation.

Why Regular 1‑Box Cleaning Matters

Many operators don’t realize how quickly DOCs, DPFs, and SCRs can become restricted. Common signs you may need 1‑box cleaning include:

• Loss of power or sluggish performance
• Reduced fuel efficiency
