Hand-cleaned DOC filters, back on the road fast.
If your truck or equipment is losing power or throwing a derate code, a clogged DOC filter is often why.
Our Services
What Our DOC Cleaning Services Actually Do
A diesel oxidation catalyst sits upstream of your DPF and does a lot of the quiet work that keeps your emissions system running clean. When it loads up with soot, oil residue, or antifreeze, your truck loses power, burns more fuel, and eventually throws a code that parks it in the shop. Our doc cleaning services and diesel oxidation catalyst cleaning process strip that buildup out and restore the filter's flow, without the cost of buying new.
We've been running this shop in Webberville since 2008, and most of our customers come back to us because we treat DOC filter cleaning with the same hands-on care as DPF cleaning. A lot of shops will bake and blow a filter and call it done. We take it further, because a half-clean DOC filter just sends the problem downstream again.
Whether you're running a single pickup or managing a yard full of semis, getting your truck emissions cleaning done right the first time saves you a second trip and a second bill. That's the whole idea behind how we built this diesel emissions system cleaning process.
Our Process
How We Handle Your DPF and DOC Cleaning Service
Every filter that comes through our door, whether it's off a school bus, a semi, or a piece of construction equipment, goes through the same hands-on steps. No automated systems, no shortcuts.
-
Step 1: Full Inspection
We check the filter for cracks, substrate damage, and the type of contamination it's carrying before anything else happens. This tells us whether we're dealing with normal soot loading, an oil contaminated DPF, or an antifreeze soaked DPF cleaning situation that needs extra attention.
-
Step 2: 14-Step Conditioning Process
This is the part most competitors skip or shortcut. Our proprietary conditioning process works contamination out of the substrate in stages instead of just blasting the surface, which is especially important for coolant contaminated or oil soaked filters.
-
Step 3: 3-Stage Testing Protocol
Once cleaned, every filter goes through flow testing to confirm it meets the restriction and back pressure specs it needs to run right. We don't hand a filter back unless it passes.
-
Step 4: Fast Turnaround
Most DOC and DPF filters go out the door within 24 hours of arrival, so your truck, tractor, or fleet vehicle is back on the road or back in the field fast. We'll call you the moment it's ready.
Know the Signs
Signs Your Diesel Filter Needs Cleaning
A lot of owner-operators and fleet managers come to us after noticing one or two of these warning signs that point to diesel emissions cleaning needs. Catching them early usually means a cleaning, not a replacement.
- Noticeable loss of power or sluggish acceleration under load
- Frequent regen cycles or a check engine light tied to emissions
- Higher fuel consumption than usual for the same routes
- White or gray smoke that points to oil contaminated DPF cleaning needs
- A sweet smell or milky residue signaling an antifreeze soaked DPF
- A dealership quote for replacement parts before anyone's checked if cleaning will do the job

Common Questions
DOC Cleaning Questions We Hear Most
How long does DOC filter cleaning take?
Most diesel oxidation catalyst and DPF filters are cleaned, tested, and ready for pickup within 24 hours of arrival. If your filter needs extra passes through our conditioning process because of heavy antifreeze or oil contamination, we'll call you with an updated timeline.
What determines the cost of a DOC filter cleaning service?
Pricing depends on the size of the unit and the type of contamination we find during inspection. We quote based on the actual unit in front of us rather than a flat industry rate, so a standard semi DPF cleaning and an antifreeze soaked DOC filter won't cost the same.
Do you handle fleet DPF cleaning for multiple vehicles at once?
Yes. We work with fleet managers and line bosses who send in several units at a time, and we can set up fleet spare filter service so a swap unit is ready whenever a truck comes in for cleaning instead of sitting parked.
What kinds of diesel equipment do you service?
We clean DOC and DPF filters for semis, school buses, pickups, tractors, cat rock trucks, and other construction and off road equipment. If it runs on diesel, we can likely clean its emissions filters rather than send you to buy new ones.
