Deep, thorough grease trap cleaning that goes far beyond pumping — full degreasing, baffle service, pipe clearing, and odor elimination for commercial kitchens.
Click Here to Call (888) 435-1815There's a difference between a grease trap that's been pumped and one that's been properly cleaned. Pumping removes the liquid and floating waste. Cleaning addresses what pumping leaves behind — the grease film coating the trap walls, the compacted material around baffles, the bacterial buildup that drives odor, the residue in inlet and outlet pipes.
King's Grease Service performs full grease trap cleaning in Delavan, WI that goes beyond extraction. We degrease the interior, inspect and clear every component, treat for odor at the source, and document the result. For commercial kitchens that need more than a surface-level service, this is the standard we work to.
After extraction, we clean the interior trap surfaces — walls, floor, and lid interior — removing the grease film that accumulates between service visits and that, left unchecked, reduces trap performance and drives bacterial odor.
All floating FOG, suspended solids, and settled sludge are extracted before any surface cleaning begins. This is the baseline — not the endpoint.
For traps with significant buildup, we use high-pressure washing to clear hardened deposits from trap walls and internal components that hand-cleaning can't fully reach.
Baffles are removed, cleaned individually, and reinstalled. If a baffle shows wear, cracking, or displacement that would compromise trap performance, we document it and provide replacement options.
Both pipes are cleared of grease accumulation as part of every cleaning service. Blockage in either line affects trap performance regardless of how clean the trap interior is.
We clean the lid interior and inspect the gasket seal. A deteriorated gasket is a common source of odor migration and should be replaced before it causes issues in adjacent kitchen areas.
After cleaning, we apply a deodorization treatment that addresses bacterial buildup — the actual source of trap odor — rather than masking it with fragrance.
Once cleaning is complete, we run a brief system check to confirm inlet flow is unobstructed, the trap is operating within normal parameters, and any components we flagged have been addressed.
Every cleaning service in Delavan generates a full service report for your records. Condition notes, components serviced, waste removed, and next service recommendation — documented and ready for review.
A grease trap that hasn't been fully cleaned — just pumped — retains the bacterial buildup that produces hydrogen sulfide and other gases. These gases travel through drain connections and can create odor problems in your kitchen or, worse, in the dining room. A full cleaning eliminates the source rather than temporarily reducing it.
Grease and solid accumulation around baffles accelerates wear. Baffles that are never cleaned — only pumped around — degrade faster and are more likely to crack or dislodge. Replacement is significantly more expensive than preventive cleaning.
In Delavan, WI, health inspectors assess not just whether a grease trap was recently serviced, but whether it's being maintained in functional condition. A trap that's been pumped but not properly cleaned may still show evidence of neglect — residue on walls, damaged baffles, corroded gaskets — that generates citations even when the service log is technically current.
Grease that isn't fully removed from trap walls and inlet/outlet pipes accumulates over time, narrowing flow capacity. Kitchens that skip full cleaning cycles often develop progressive drain restriction that becomes a hydro jetting job instead of a standard cleaning — a significantly higher service cost.
A grease trap is one component in a connected system. Its performance depends on everything upstream and downstream operating properly.
Upstream: the drain lines running from sinks, floor drains, and cooking equipment to the trap. If these are coated with grease, your trap fills faster than it should and your service intervals compress. Drain line degreasing, done alongside trap cleaning, resets the whole system — not just the trap itself.
Downstream: the sewer connection at the trap outlet. If the outlet pipe is partially blocked, backpressure builds inside the trap, which accelerates baffle wear and increases the risk of overflow during high-volume service hours.
When we clean a grease trap in Delavan, we look at the whole picture. Inlet line condition, outlet flow, baffle integrity, lid seal. If something connected to the trap is working against it, we tell you — because fixing the trap without addressing connected issues just means the problem returns faster.
Most grease trap service is organized around getting in and out quickly. That's not how King's Grease operates.
We approach each cleaning as an inspection opportunity. Every surface we clean is a surface we can assess. Every component we handle is a component we can evaluate for wear. The service report you receive at the end of a King's Grease cleaning visit includes condition notes that track changes over time — so if a baffle is showing early wear, you know about it on the third visit, not when it fails on the eighth.
We also schedule around your operation. Grease trap cleaning doesn't need to disrupt service. We coordinate with your kitchen schedule to work during prep windows, between service periods, or during closings. In Delavan, WI, we service kitchens across the full range of operating hours because that's what the business requires.
"We'd been getting basic pump-outs from another company for two years and still had persistent odor coming from the floor drains. King's Grease came in, did a full clean, and identified a cracked baffle that had never been caught. The odor issue was gone after one proper service."
"The service reports they provide are genuinely useful. We can see how the trap condition is tracking over time, which has helped us adjust the cleaning frequency for different times of the year when our volume changes."
"I appreciate that they check the drain lines when they service the trap. We had a slow drain situation developing upstream that they caught before it became a problem. It's the kind of thoroughness I wasn't getting from the previous company."
If your trap has been pumped but never properly cleaned — or if you've been dealing with persistent odor, slow drains, or compliance documentation gaps — King's Grease Service is ready to give it a proper service.
