Introducing the GP DPF & Catalytic Foam Cleaner

Clean Smart, Drive Cleaner

GP is proud to launch a game-changer in vehicle maintenance:
The GP DPF & Catalytic Foam Cleaner a simple, safe, and powerful aerosol solution designed for on-vehicle cleaning of diesel particulate filters DPF and catalytic converters without removing them. Ideal for city cars, stop-and-go traffic, and regular service intervals.

Key Benefits at a Glance

Benefit What It Means for You

No Removal Required: Installs in seconds via sensor port no dismantling or downtime.

Fast & Efficient Foam: penetrates deep soot and carbon deposits within ~20–30 minutes.

Eco & Budget Friendly: Helps avoid costly replacements or workshop cleanings.

Versatile & Safe: Compatible with both diesel DPF and gasoline catalytic systems.

Supports Regeneration: Promotes safe burning-off of residues during normal driving.

The GP DPF & Catalytic Foam Cleaner  uses a targeted, non-dismantling method to restore flow and efficiency in diesel particulate filters DPFs  and catalytic converters. Here's how the process typically works:

Step-by-Step Cleaning Process 

1.  Inspection & Diagnosis   

Before applying the foam, technicians often scan the vehicle for fault codes and check back pressure levels to confirm DPF or catalyst blockage. This helps determine whether chemical cleaning is suitable or if deeper intervention is needed.

2. Foam Injection  

The cleaner is sprayed directly into the DPF or catalytic converter via a long, flexible nozzle. The foam expands inside the component, penetrating deep into the honeycomb structure where soot, ash, and carbon deposits accumulate.

3. Chemical Breakdown  

 The active ingredients in the foam dissolve stubborn contaminants especially carbon and sunburn hydrocarbons without damaging the ceramic substrate or catalytic coating. This is a key advantage over heat-based or ultrasonic methods, which can be more invasive.

4. Soak & Dwell Time 

After application, the foam is left to soak for a designated period (usually 15–30 minutes), allowing the chemical reaction to fully break down deposits.

5. Flush & Rinse   

In some cases, a follow-up rinse or compressed air flush is used to remove loosened debris.This step ensures that the channels are clear and the cleaner residue is expelled.

6. Engine Regeneration 

Once the foam has done its job, the engine is started and run at elevated RPMs to trigger a forced regeneration. This burns off any remaining soot and confirms restored flow through the exhaust system.

7. Final Check 

A post-cleaning pressure test or scan confirms that back pressure has dropped and the system is functioning properly. 

This validates the effectiveness of the cleaning.

 Why It Works Well in the UAE 

Given the high ambient temperatures and frequent short-trip driving patterns in the region, DPFs are prone to premature clogging.
This foam-based method offers a quick, workshop-friendly solution without dismantling or downtime.
