JLM Diesel DPF Spray is a high‑strength aerosol cleaner designed to quickly dissolve soot, carbon, and particulate build‑up inside diesel particulate filters — without dismantling the DPF. It’s the fastest, most cost‑effective way for workshops to get vehicles back on the road while maintaining strong profit margins.
Illuminated DPF warning lights
Failed particulate/emissions tests
Short‑trip driving habits
Loss of power or rising fuel consumption
Short journeys and low exhaust temperatures prevent proper regeneration, causing soot accumulation. JLM Diesel DPF Spray restores full DPF flow, helping the engine breathe again and perform as intended.
JLM Diesel DPF Spray contains a high concentration of active cleaning agents that:
Break down soot, carbon, and particulate deposits
Lower the combustion temperature of trapped particulates
Allow faster, earlier burn‑off during forced regeneration
Restore exhaust flow and reduce backpressure
Use the spray directly into the DPF prior to a forced regeneration (test drive or OBD). The result: a cleaner filter, improved engine performance, and a higher chance of passing emissions testing.
No DPF removal required
Quick turnaround for customers
Strong margin opportunity
Effective on stubborn short‑trip soot loading
Compatible with all diesel engines and all DPF types
One can treats one DPF. The formula is non‑flammable, ash‑free, metal‑free, and evaporates without residue.

Personal protection is essential when working with aerosol cleaners and hot engine components.
Put on gloves and safety goggles
Ensure the workspace is well‑ventilated
Heating the engine ensures the DPF and surrounding components reach optimal cleaning temperature.
Start the engine and let it reach normal operating temperature
Switch the engine off before proceeding
Removing sensors provides direct access to the DPF for proper spray application.
Locate the temperature and/or pressure sensor
Carefully remove the sensor(s) to expose the DPF inlet
The spray dissolves soot and carbon deposits inside the filter.
Insert the spray pipe and nozzle into the sensor opening
Spray the entire contents of the can into the DPF
Ensure even distribution throughout the filter
Sensors must be refitted before regeneration to ensure correct system readings.
Refit the temperature and/or pressure sensor securely
Adding DPF Cleaner enhances the regeneration burn‑off process.
Pour JLM DPF Cleaner into the fuel tank before regeneration
Regeneration burns off loosened soot and completes the cleaning process.
Use a diagnostic tool to initiate forced regeneration
Alternatively, perform a test drive to trigger regeneration
Final system checks ensure the vehicle leaves the workshop without warnings.
Scan the ECU for error codes
Clear any stored faults after successful regeneration
