Restaurant Exterior Cleaning Equipment — The Complete Checklist for Commercial Kitchen Contracts
Updated May 2026 | By Powerline Industries
Restaurant exteriors are the single greasiest commercial cleaning job on the market. Dumpster pads, drive-thru lanes, kitchen exhaust hood discharge points, sidewalks coated in fryer grease blow-off — none of it comes clean with a cold-water residential pressure washer and a bucket of degreaser. If you’re bidding restaurant work with the wrong rig, you’re either losing money on every job or losing the job entirely to the operator who specced his equipment right.
This is the equipment checklist we walk through with every contractor who tells us they want to land restaurant accounts. Built off 50+ years manufacturing for commercial operators and 2,500+ units in service.

Why Restaurant Exteriors Are Different
Most commercial pressure washing — parking lots, building exteriors, sidewalks — is a dirt removal job. Restaurant work is a grease removal job. That’s a fundamentally different chemistry problem and it requires fundamentally different equipment.
Here’s what you’re actually dealing with on a restaurant exterior:
- Dumpster pads — months of food waste leachate, animal fat, bacterial buildup. Health code violations if not handled.
- Drive-thru lanes — fryer grease blowout from exhaust fans, soda drips, oil spots from idling cars.
- Kitchen exhaust hood discharge zones — the rooftop or sidewall where the kitchen exhaust dumps aerosolized cooking grease. It coats everything within 20 feet.
- Concrete pads at the kitchen back door — the highest-traffic grease zone on the property. Bus tubs, mop water, oil drums.
- Sidewalks and entrances — gum, food drips, beverage spills, traffic grime.
Cold water spreads grease around. Hot water dissolves it. That’s the entire game.
Why You Need Hot Water (Non-Negotiable)
We’ll say it plain: if you’re bidding restaurant work without hot water, you’re competing on price alone — and you’ll lose to anyone who can actually deliver clean results. The math is simple. Animal fats and cooking oils have melting points between 90°F and 130°F. Below that range, grease is a solid film bonded to concrete. Above it, grease flows.
A Powerline hot water trailer hits the surface at 180°F to 200°F. That’s not “warm.” That’s the temperature that turns a four-hour scrub job into a 45-minute walk-and-spray. And the surface comes truly clean — no greasy film left behind to attract dirt and re-coat the area within a week.
Cold water on restaurant grease? You’re emulsifying it, spreading it across a wider area, and watching it re-solidify two feet downstream. The property manager who hired you sees the same spot dirty again in five days and finds another contractor.
If you only read one section of this article, read this one: hot water is the spec that wins restaurant contracts. Everything else is a refinement on top of that.
The Equipment Checklist for Restaurant Work
Here’s the rig spec we recommend for an operator who wants to land and keep restaurant accounts:
| Equipment | Spec | Why |
|---|---|---|
| Hot Water Pressure Washer | 5.5–8 GPM at 3,500 PSI, 180°F+ output | Dissolves animal fat and cooking oil at the molecular level |
| Schedule 80 Heating Coil | Heavy-wall, commercial grade | Lightweight coils crack under daily heavy use — Powerline coils are built for 8-hour cycles |
| Water Tank | 300–525 gallon on-board | Most restaurants don’t have a clean spigot you’d want to use. Bring your own water. |
| Downstream Chemical Injection | Single or dual injection | Apply alkaline degreaser through the gun for dumpster pads and grease zones |
| Surface Cleaner | 20″–24″ rotary, hot water rated | Concrete pads and drive-thrus go 4x faster with a surface cleaner vs wand |
| Water Recapture System | Berm + vacuum recovery | Required by most municipalities — grease-laden runoff cannot enter storm drains |
| Hose Reel | 200 ft high-pressure + 100 ft chemical | Restaurants are tight properties — long hose runs save you from constantly repositioning |
The non-obvious items on this list are the ones that separate operators who land repeat work from operators who get fired after one cleaning. Specifically:
- Water recapture — Most municipalities will fine the property owner if you discharge grease-laden water to a storm drain. The property manager is liable, not you, but they’ll never call you back. Bring berms and a recovery vacuum.
- Schedule 80 coil — Cheap coils crack within 12 months of daily commercial use. Powerline runs Schedule 80 because the warranty replacements on thin-wall coils would have put us out of business decades ago.
- On-board tank — Restaurant spigots are often inside the kitchen (you don’t want to drag a hose through there) or shut off after hours. Bring your water.
How This Equipment Changes What You Can Bid
An operator with a 4 GPM cold-water rig and a residential surface cleaner is bidding $0.08–$0.12 per square foot for restaurant work, hoping volume covers thin margin. He’s losing money on dumpster pad work and probably skipping it.
An operator with the rig spec above bids $0.15–$0.25 per square foot, charges $150–$300 per dumpster pad as a separate line item, and offers a 30-day satisfaction guarantee because he knows the work will hold. He lands the regional accounts — chains with 20+ locations on monthly service contracts.
One regional QSR account at 15 locations, cleaned monthly at $400 per location, is $72,000/year of recurring revenue from a single relationship. That’s the math that justifies the equipment.

FAQ
Do I need a separate trailer for restaurant work, or can I use my existing rig?
If your existing rig has hot water, 5.5 GPM+, and downstream chemical injection, you can run restaurants on it. If you’re running cold water only, you’ll need to either upgrade or stay out of the restaurant vertical. There’s no workaround for the grease chemistry.
How do I handle wastewater on restaurant jobs?
Bring a containment berm, a wet-vac with a degreaser-rated filter, and discharge to either a sanitary clean-out (with property manager permission) or to your tank for proper disposal off-site. Never discharge to storm drains. EPA penalties are severe and the property owner is on the hook.
What’s the right water temperature for restaurant exteriors?
180°F minimum at the surface for grease zones. 200°F if you’re hitting a heavily caked dumpster pad. Below 160°F you’re just spreading the grease around, and the property manager will see the same spot dirty in a week.
Can I clean kitchen exhaust hoods with this same equipment?
No — hood interior cleaning is a separate certification (typically IKECA) and requires different equipment, chemicals, and insurance. The equipment in this article is for exterior cleaning only: pads, drive-thrus, sidewalks, rooftop discharge zones, dumpster areas.
