Built for grease that soap and water gave up on

Grill grease is not ordinary kitchen grime. Fat drips onto hot metal, polymerizes and turns into a hard carbon shell that ordinary dish soap slides straight off. Grease Killer Spray is a concentrated alkaline degreaser that soaks into that layer and breaks the bond so it lifts instead of smears.

  • Softens baked-on carbon on cast iron and stainless grates
  • Cuts sticky residue on flavorizer bars, heat plates and grease trays
  • Works inside the house too — ovens, hoods, stovetops, air fryer baskets
  • No wire-bristle scrubbing marathon needed on most buildup
  • Trigger sprayer: no mixing, no soaking tubs, no mess

Three steps, about five minutes of waiting

1. Spray a cool surface

Grill off and fully cool. Coat the greasy area evenly — grates, bars, trays, oven walls.

2. Let it dwell 3–5 minutes

The dwell time is where the work happens. Heavy carbon can take a second application.

3. Wipe and rinse

Agitate with a brush or pad, wipe away, then rinse food-contact surfaces with clean water.

Safe-use notes

  • • Cool surfaces only. Never spray a hot or lit grill.
  • • Keep it out of burner tubes, burner ports and electrical igniters.
  • • Spot-test painted panels, aluminum, anodized finishes and unsealed stone.
  • • Rinse food-contact surfaces thoroughly with clean water before your next cook.
  • • Wear gloves, work in ventilated areas, and follow the label on your bottle — the label always overrides this page.

What buyers say

"Two seasons of baked-on drippings on my Weber. Sprayed it, waited five minutes, and most of it wiped off with a rag. I still scrubbed the corners, but this cut the job from an hour to fifteen minutes."
Marcus T. · Austin, TX · 3-bottle bundle
"Bought it for the grill, ended up using it on the oven door and range hood filter. The hood filter was the biggest surprise — it came out looking new."
Dana R. · Columbus, OH · 5-bottle bundle
"Not magic, you still have to wipe. But it's the first thing I've used that softened the carbon on my flavorizer bars instead of just smearing it around."
Bill K. · Sarasota, FL · 2-bottle bundle

Frequently asked questions

What is Grease Killer Spray used for?
It is a heavy-duty degreaser formulated for baked-on grease and carbon: grill grates, flavorizer bars and heat plates, drip pans and grease trays, oven interiors, range hoods, stovetops, air fryer baskets and greasy kitchen surfaces.
How do I use it on a grill?
Work on a cool grill only. Spray an even coat onto the greasy surface, let it dwell for 3–5 minutes so it can soften the buildup, agitate with a brush or pad, then wipe and rinse thoroughly with clean water before your next cook. Heavy carbon may need a second pass.
Is it safe on grill grates that touch food?
Treat it like any cleaning chemical: use it on cool surfaces, keep it off open flame and burner ports, and rinse food-contact surfaces thoroughly with clean water before cooking. Always follow the directions and warnings printed on the bottle you receive — the label overrides any web page.
Which surfaces should I avoid?
Spot-test first on painted panels, aluminum, anodized finishes, unsealed natural stone and delicate plastics. Do not use it on hot surfaces, inside burner tubes, on electrical igniters, or on anything the label warns against.
How many bottles do I need?
One bottle is enough for a few deep cleans on an average gas grill. Most buyers pick the 3-bottle bundle so they can keep one at the grill, one in the kitchen and one in the garage. The 5- and 8-bottle bundles bring the per-bottle price down to $11 and $9.
How much does shipping cost and how fast is it?
Orders of two bottles or more ship free inside the United States. Single bottles have a $4.95 flat shipping charge. Orders are packed within 1–2 business days and typically arrive in 3–7 business days. Priority + insured delivery is an optional $9.95 upgrade at checkout.
Do you ship outside the US?
Right now this store ships to United States addresses only, including APO/FPO. We are working on adding more destinations.
What if it does not work for me?
Every order is covered by a 90-day money-back guarantee. Email contact@qualitygrillparts.com with your order number and we will walk you through the return and refund.
Is checkout secure?
Yes. Payments are processed by Stripe over an encrypted connection. We never see or store your full card number, and your card details never touch our servers.
Will it remove rust or repair damaged parts?
No. It is a degreaser, not a rust converter or a repair product. If your grates are rusted through or your burner tubes are cracked, cleaning will not save them — see our replacement-part guides instead.
