How to Clean a DPF


Here’s the correct way to clean a DPF…

Most mechanics are still unsure about DPF Cleaning and sending them away can take time, causing a lost opportunity to gain extra profit for your garage. Here’s how easy it is to restore a DPF, and most of our machines have an automatic feature meaning that even a junior mechanic can perform a deep clean in just 20 minutes! 
Take a look…

Firstly, Why does a DPF get Blocked?

Usually around every 300 miles or so the DPF will regenerate by super-heating the filter to burn off the contaminated particles that collect there as soot and ash. Most of the soot is then expelled through the exhaust as finer particles of harmless ash. However, it has been found that the regeneration process leaves residual ash behind in the filter. Each time a regeneration occurs more particles will build up in the filter.

Over time carbon will block the DPF and cause several issues within your engine. The Carbon-Clean DPF ProClean Treatment, when used alongside our DCS machines, is a fast and cost effective way to completely clean and protect any DPF. Our range of machines offer fast, simple and effective cleaning of the DPF filter from within the workshop.

Step 1

Remove the blocked DPF from the vehicle. This is normally a straight forward job for most mechanics. Our machines can restore passenger vehicle DPFs to even HGV commercial DPFs!

Step 2

Soak the DPF in our specially formulated ProClean solution for 20 minutes. This loosens up the hard, unburnt soot and ash, and prepares the DPF for a thorough clean.

Step 3

The DPF is then connected securely to our high quality machines which come with all types of accessories to fit any DPF. The accessories include various nuts and bolts to block out any O2 sensor holes (and others) for effective cleaning.

Step 4

High pressure air and water is then pumped through to thoroughly clean all parts of the DPF in just 20-30 minutes. Some of our machines incorporate features to show before/ after pressure readings, and even have a dryer for quicker turnaround times.

Step 5

The DPF is now restored and can be installed back to the vehicle. We also suggest using our ProClean Power & Protect solution which coats the DPF, to slow down the carbon build-up again.
