Has anyone clean their DPF filter by pressure washing it. If so, what were your results.

Highly discouraged. When doing so you usually wash away the metals inside the honeycomb and the DPF overall becomes less effective and more likely to clog in the short term.

Only do it as a band aid and you are planning to demandate very soon. Also, if filter is becoming full too soon the issue may be the engine, the filter doesnt cause problems, but will make it obvious you have an engine problem.

It’s a guaranteed fix if you pressure wash your dpf…… I guarantee you will have to fix it after you pressure wash it. Not being an ass just letting you know it only gets you by for a very short time. Not to mention you will just push the soot to the center of the filter and clog it which could potentially damage your engine, etc…. You really need to look at a diagram of how a dpf filter is designed to completely understand this

bad idea all together...
it has been talked about plenty of times on here before, and the sad part is that there are plenty of youtubes videos that would say otherwise,.. like a bunch of bad information, spreading like a virus.

Savannah river sight brought me an mru Mack garbage truck with a glowing red dpf filter. Supposedly the filter had cleaned and passed but after asking the right questions to the right people I found out that they soaked the dpf in peanut oil…..yes peanut oil, and pressure washed it….. because they seen it online. Needless to say the shi#t didn’t work. If it were that easy air knives and ovens wouldn’t exist to clean them. Pressure washing your dpf would have a service interval.
