Diesel EGR Cleaner

Diesel EGR Cleaner is a water based product that safely and efficiently removes even heavy soot and carbon deposit buildup from diesel engines equipped with EGR systems.

The Problem

Carbon and soot deposits build up and cause improper EGR valve operation, sticking vanes in the turbocharger, and blockages in the EGR cooler and DPF. These deposits cause drivability problems and reduce power, performance, and fuel economy. Frequent idling and stop-and-go driving speed up the accumulation of deposits and blockages, which if not removed, will result in the need for component replacement.

The Solution

Bardahl PRO® Diesel EGR Cleaner & Diesel EGR Rinse is a 2-step process designed to clean EGR valves, turbochargers, intake manifolds, EGR coolers and DPF. Diesel EGR Cleaner is a water-based solution safe for Diesel engines and is designed to be used in conjunction with Bardahl Diesel EGR Rinse (#94360) to remove any cleaning residue or remaining deposits. Use with a professional diesel EGR cleaning machine diesel EGR canister delivery system or soak dirty components in a bath of the cleaner, rinsing upon completion.


  • Restores proper EGR valve operation.
  • Cleans sticking variable vanes in turbocharges.
  • Removes blockages in EGR and exhaust systems, including the DPF.
  • Cleans the entire induction system including intake valves and combustion chambers.
  • Restores power, improves performance, and increases fuel economy.
  • Safe for use with all diesel emissions control systems, including DPFs and catalytic converters.


The cleaning and rinse solutions can be applied in a 2:1 ratio or 1:1 ratio of cleaner to rinse depending on deposit severity. Use either a diesel EGR canister delivery system or a diesel EGR cleaning machine that can accommodate a 2-step process and water-based chemicals. Follow the instructions of the equipment manufacturer regarding how to connect the canister or machine to the vehicle and properly use the solution to conduct a professional service. The EGR cleaner must be applied first and run through the engine, followed by the EGR rinse to remove any residual cleaner. An oil change is recommended after conducting this service. Perform the service every 15,000 to 30,000 miles or as recommended by a technician. This product can also be used to effectively soak and clean DPF filters. Dispose of any used or unused solution and the container in accordance with local, state, or federal regulations.
