A printable walk-through for checking your grill before and after a clean — what to look at, what good looks like, and the points where the right move is to stop and call someone qualified. Free to use, print and share.
Read your grill’s manual first — it overrides any general guidance
Make sure the grill is completely cold, not just switched off
Turn all control knobs to off
Shut off the fuel supply following the manufacturer’s instructions — close the cylinder valve on LP, or the appliance shutoff valve on natural gas
Charcoal or pellet: confirm there are no live embers before touching anything
Have gloves and eye protection to hand
Work outdoors, in daylight, with the grill on a stable, level surface
Grease and residue — the fire risk
Check for grease or fat buildup on the cooking grates (NFPA identifies keeping the grill clean of grease and fat buildup as a core grilling safety practice)
Check the trays and pans below the grill — NFPA calls these out specifically
Look underneath and behind the grill, where grease collects out of sight
Look for pooled or hardened grease in the bottom of the cook box
Note any history of flare-ups or heavy smoke during cooking — usually a buildup symptom
Grates and cooking surfaces
Lift the grates out and look at what is underneath — this is where the real buildup lives
Check grates for heavy carbon crust, flaking, warping or rust-through
Check radiants, flavour bars, heat tents or briquettes for buildup and damage
Note whether any rust is on the surface or has gone through the metal — the difference decides whether cleaning helps
Burners and burner ports
With the grates and shields out, look along each burner tube for even, open ports
Look for split, cracked or rusted-through burner tubes — these are replacement parts, not dirt
Check for insect nests or webbing in and around burner and venturi tubes — CPSC advises checking for and clearing obstructions such as spider webs, which can block gas flow
Do not modify, drill out, straighten or repair a burner — a damaged burner is replaced, not fixed
If a burner looks damaged or obstructed, stop and contact a qualified professional or the manufacturer
Grease-management components
Remove and empty the grease tray, cup or catch pan
Clear the drain path from the cook box to the tray — a blocked path is what makes grease pool
Replace disposable grease liners if your model uses them
Check the tray is seated correctly when it goes back
Hoses, connections and the cylinder
Visually check the hose for cracking, brittleness, holes, splits or wear — CPSC advises inspecting hoses for exactly these
Check the hose is not kinked and has no sharp bends
Check the hose is routed clear of hot surfaces and is not resting against the firebox
Keep LP cylinders upright, and never store a spare cylinder under or near the grill or indoors — CPSC guidance
Do not attempt to repair a cylinder valve or regulator yourself — CPSC advises seeing an LP gas dealer or a qualified appliance repair person
If you smell gas at any point: stop, do not light the grill, keep flames and ignition sources away, and follow your manufacturer’s and LP supplier’s instructions
Ignition check
With everything reassembled and the fuel supply restored per the manual, open the lid before lighting — NFPA advises making sure the lid is open before you light a gas grill
Confirm each burner lights and stays lit
Look at the flame across each burner: it should be largely blue and even along the tube
Yellow, lazy or missing flame over part of a burner usually means blocked ports or a damaged tube
If a burner will not light, lights unevenly, or you suspect a fault — stop and contact a qualified professional
Placement and clearance
Use the grill outdoors only — both CPSC and NFPA are explicit that grills are never for indoor use
Position the grill well away from the house, deck railings, eaves and overhanging branches (NFPA)
CPSC guidance advises using the grill at a distance from the house or any building
Keep children and pets well clear of the grill area — NFPA advises a three-foot zone
Never leave a lit grill unattended (NFPA)
Check whether your building, association or municipality restricts grill use or fuel type at your address — rules vary and this checklist does not interpret them
After cleaning — final inspection
Confirm every component removed has gone back in the right place and orientation
Confirm the grease tray and drain path are clear and correctly seated
Confirm the hose and connections are secure, unkinked and clear of hot surfaces
Test-fire each burner and confirm an even flame
Confirm the work area is clean and no degreaser residue is left on surrounding surfaces
Note anything cleaning could not fix — corrosion, pitting, discoloured finishes, failed parts — so you know what you are dealing with next season
Stop and call a professional if
You smell gas, or suspect a leak
A hose is cracked, split, brittle or damaged
A burner tube is split, cracked or rusted through
The firebox or lid has rusted through, or flexes under hand pressure
The igniter fails and clearing the burner ports has not resolved it
The regulator or cylinder valve appears damaged
Anything about the grill’s operation seems unsafe, or you are simply unsure
This checklist covers cleaning and visual inspection of a residential grill. It is not a repair guide. Always follow your grill manufacturer’s manual, which takes precedence over anything here.
Educational guidance only — not an inspection, a safety certification, or a substitute for your manufacturer’s instructions. Chicagoland Grill Cleaning is a grill cleaning service: it is not a gas technician, an appliance repair company, a fire inspector, a code authority or a manufacturer-authorised servicer. If you suspect a gas leak, damage, corrosion or unsafe operation, stop, shut off the fuel supply following your manufacturer’s instructions, and contact a qualified professional or your LP gas supplier. Local rules on where and whether a grill may be used vary by municipality, building and association — check with yours.
Where This Comes From
Sources
Safety guidance on this page is paraphrased from, and attributed to, public guidance published by the bodies below. Where they give no guidance, this checklist gives none. Your grill manufacturer’s manual takes precedence over all of it.
This list keeps you on top of what you can see. A professional deep clean is a teardown — grates, radiants and shields out, cook box scraped and degreased, grease path cleared, burners cleaned and inspected. If the list above turned up heavy carbon, pooled grease, or something that looked failed rather than dirty, that is the point to ask.
The more you can describe the grill and its condition, the more accurately it can be quoted — and the fewer back-and-forth messages before you get an answer.
Describe the grill once — type, size, condition
Add photos now, or send them after the first call
Mobile Service — scope and price confirmed before any work
Chicagoland Grill Cleaning helps homeowners document their grill’s condition and connect with an available local grill-care professional. Submitting this form sends a request — it is not a confirmed booking. The professional who picks it up confirms scope, pricing and availability with you directly before any work happens.
