DPF, catalyst and SCR

SCR and catalytic converter cleaning with one fluid

If you clean particulate filters, the catalysts and SCR units that come in with them do not need a second chemical. DPF Cleaner handles soot, baked-on combustion residue and urea deposits with the same method: in the machine or in a heated bath, at the same dilution, with a dwell time that depends on the fouling.

One product on the shelf

One concentrate for DPF, catalyst and SCR means one product to stock, one safety data sheet to sign off and one dilution on the board. The only thing that changes per part is how long it stays in.

Urea deposits on SCR units

SCR units come in with urea deposits from AdBlue as well as soot. The method is the same as for a filter: blow out the loose material, put the unit in the heated machine or bath at 1:10 or 1:5, let it work and rinse with clean water.

The dwell time differs per type of fouling. Check the unit and give heavy deposits more time rather than a stronger mix.

Loose parts in the same fill

Anything with soot or baked-on combustion residue that you can submerge can go through the same fill: exhaust sections, turbo parts, grilles and housings. Rebuild shops often do this in an immersion bath or an ultrasonic tank, at the same dilution.

Catalyst or SCR unit, step by step

  1. 01

    Inspect and blow out

    Check the substrate for cracks or melting, then blow out the loose material dry with compressed air.

  2. 02

    Dose

    1:10 for normal fouling, 1:5 for heavy deposits. Machine or bath at 60 to 70 °C.

  3. 03

    Let it work

    30 to 60 minutes as a starting point. Heavy urea deposits get more time, not a stronger mix.

  4. 04

    Rinse and dry

    Rinse with clean water until it runs clear and dry fully with warm air before the part is refitted.

What it does not do

  • It does not repair a cracked or melted substrate.
  • It does not replace diagnosis of the dosing system or the sensors on the vehicle.
  • It is never added to the AdBlue tank or the fuel tank.
  • It should not stand undiluted on aluminium or painted parts.

Questions

What filter cleaners ask.

Can I clean the DPF, the catalyst and the SCR unit in the same tank?

Yes. It is the same method and the same dilution. Only the dwell time differs per type of fouling.

Does it remove urea deposits?

Yes, SCR units with urea deposits are one of the applications. Heavy deposits get a longer dwell time rather than a higher dose.

Does an alkaline fluid damage the substrate?

Not at the recommended dilution and dwell time. What you avoid is using it undiluted, and leaving it on aluminium or painted parts.

Which pack sizes are there?

1, 5, 10, 20, 200 and 1000 litres. The price per litre drops with the volume; the order block shows it per pack size.
