Our process 

Scrolling down you'll find a complete and concise description of what we do when we clean a DPF, from when we receive it to the point when we complete the process and send it back to the customer or refit it to your car.

1.Before the cleaning process can begin, a test form is created. This will become a unique record of the customers DPF.

2. A visual inspection is made looking for physical damage to the DPF, usually using a "bore scope".

3. A flow test is carried out. Pressurised air is forced into the DPF at a set pressure using a monometer.

4. The filter is then cut open. This enables us to get to the whole face of the DPF and guarantee a thorough clean.

5. We then weigh the filter, this will give us a comparison reading at the end of the cleaning part of our process.

6. Prewash.This flushes out any loose particles of carbon, soot and ash contaminates inside the filter.

7. The DPF goes through a 30 minute cycle of ultrasonic cleaning. This process is repeated until the filter is clean.

8. The Kiln. This dries out the DPF. 675 degrees for 90 minutes, also replicating a regen and turning any left over particles to ash.

9. Air lanced to remove any final particles then on to re-weighing to see how much has been removed from the DPF.

10. The filter is then welded back together and tidied up before respraying to complete the reconditioning.

11. Final stage of the paperwork. The test form is completed and a copy kept for our records for and attached to the invoice.

What we do is completely recondition a DPF cheaper than the price of a clean. Nobody else goes to the lengths The DPF Cleaning Co goes to when it comes to DPF cleaning.
