Diesel Emissions System Cleaning
DPF and DOC Combination Cleaning for Lansing Area Diesel Fleets
When both filters are clogged, one visit keeps you from paying for two appointments. We clean your DPF and DOC together and get you back on the job within 24 hours.
Why Choose Us
Why DPF and DOC Cleaning Go Together
A diesel particulate filter and a diesel oxidation catalyst sit next to each other in the exhaust stream, and when one gets dirty, the other usually isn't far behind. That's why we treat diesel particulate filter cleaning and diesel oxidation catalyst cleaning as one job, our dpf and doc cleaning service, instead of two separate appointments.
Running a derate code, losing power on hills, or watching your regen cycles get more frequent? These are classic signs both components need attention at once. Our dpf doc cleaning service handles the inspection, cleaning, and testing of both filters together so you only make one trip to Webberville and only pay for one turnaround.
This combination service, essentially a diesel emissions filter cleaning done in one visit, is popular with owner-operators and fleet managers who want one invoice, one pickup, and one truck back on the road rather than juggling two separate filter jobs on two different schedules.
Our Hands-On Process
How We Clean Your DPF and DOC Together
Every filter that comes through our door gets the same personal attention, whether it's off a pickup or a semi. Here's how a combination job moves through our shop.
-
Step 1: Joint Inspection
We pull both the DPF and DOC and inspect them together, checking for ash loading, soot buildup, cracks, and any oil or antifreeze contamination that could point to a bigger engine issue.
-
Step 2: 14-Step Conditioning Process
Both filters go through our exclusive 14-step conditioning process, a thorough diesel filter flushing and cleaning cycle that we developed ourselves and still run by hand on every unit.
-
Step 3: Hydrocleaning and Flushing
Where competitors stop at a basic blow and bake, we add a hydrocleaning and flushing stage to break loose stubborn soot and ash that heat alone won't remove from either the DPF or the DOC.
-
Step 4: 3-Stage Testing Protocol
Before anything leaves our shop, both filters pass through our 3-stage testing protocol to confirm proper flow and back pressure, so you know they're ready for real work, not just clean to the eye.
Know When You Need This Service
Signs Your Truck Needs DPF & DOC Combination Cleaning
Most of our combination cleaning customers come to us after noticing more than one warning sign at once. If any of these sound familiar, it's worth a call before you spend money on new parts.
- Frequent or failed regeneration cycles on your diesel truck or equipment
- Derate codes paired with noticeable power loss
- A history of oil contaminated dpf cleaning or antifreeze soaked dpf cleaning needs on the same unit
- Rising exhaust backpressure readings on fleet diagnostics
- A DOC that's never been serviced even though the DPF has
- Equipment nearing the mileage or hour mark where both filters typically load up together
Catching both issues in the same visit usually costs less than replacing either part, and it keeps your truck, tractor, or school bus out of the shop for good.
Why Choose Us
Why Lansing Area Fleets Choose Us for Combined Filter Work
We've been doing this as a hands-on, two-person operation since 2008, and we still answer the phone and work the filters ourselves. Here's what that means for a combination cleaning job.
-
No Automated Systems, No Shortcuts
We stubbornly refuse to run filters through automated machines. Every DPF and DOC that comes through our shop gets inspected, conditioned, and tested by hand, start to finish.
-

We know a truck sitting idle costs you money. Most dpf doc cleaning service jobs, including combination work, go back out the door within 24 hours of arrival.
-
Built for Commercial and Domestic Diesel
Whether it's a domestic diesel truck, a semi, a cat rock truck, a tractor, or a school bus, we service anything with a diesel engine, and we often save parts a dealership would mark unserviceable.

Common Questions
DPF & DOC Combination Cleaning Questions
How is combination cleaning different from cleaning just one filter?
We pull and inspect both the DPF and DOC in the same visit, run them through our conditioning and hydrocleaning process together, and test both before your truck leaves. It's one appointment, one invoice, and one trip instead of scheduling two separate DPF filter cleaning service appointments weeks apart.
Do you handle semi trucks and commercial fleet dpf cleaning, or just light trucks?
Both. We regularly do semi dpf cleaning, commercial truck dpf cleaning, and commercial fleet dpf cleaning jobs for fleet managers, alongside domestic diesel truck work for individual owner-operators. We also service tractors, school buses, and heavy equipment like cat rock trucks.
Can you clean an oil or antifreeze contaminated filter as part of a combo job?
Yes. Oil contaminated dpf cleaning and antifreeze soaked dpf cleaning both add a step to our conditioning process, but we build that into the same turnaround whenever possible. Let us know when you drop off or call ahead so we can plan the right process for your filter.
What's the turnaround time for a DPF and DOC combination service?
Most combination jobs are back out the door within 24 hours of arrival. If your filters show heavy contamination or need bung repair in addition to cleaning, we'll give you a realistic timeline before we start work, not after.
