How grease management works
Drippings that aren't vaporized by the heat plates fall to the bottom of the firebox, which is sloped or funneled toward an opening. Below that opening is a grease tray or drip pan, sometimes with a smaller grease cup or disposable liner. On built-ins, the tray usually slides out from the front below the burners. On freestanding grills it's often accessible from the back or through the cart doors.
It's a simple system, and when it works you barely think about it. When grease can't reach the tray, or the tray can't hold it, the trouble starts.
What goes wrong, most common first
Overflowing tray
Trays that never get emptied fill up, and grease spills into the cabinet or onto the patio.
Clogged firebox opening
Grease and debris block the path to the tray, and grease pools in the firebox where it can ignite.
Learn moreRusted-through drip pan
Grease and moisture eat through steel trays. Grease leaks into the cabinet below.
Warped or bent tray
Heat or a grease fire warps the tray so it no longer slides in or catches drips properly.
Missing tray or wrong replacement
We see grills running with no tray, or with one that doesn't line up with the firebox opening.
Rodents
Grease attracts mice and rats. They nest nearby and chew hoses and wiring.
Learn moreWhat you can safely do
- Let the grill cool completely before touching the tray. Hot grease burns.
- Slide out the tray and empty it into a container you can throw away. Don't pour grease down a drain or onto the ground.
- Line the tray with foil or a disposable liner if the grill allows it, so cleanup is easier.
- With the grates and heat plates out, scrape the firebox floor toward the tray opening.
- Look at the tray for rust holes, warping, or signs it isn't lining up with the opening above.
- Check the cabinet floor below for grease leaks.
How we repair grease management
- 1
Deep clean the firebox
Built-up grease is scraped and degreased with biodegradable cleaners, and the path to the tray cleared.
- 2
Inspect the tray and slides
We check the tray, liner, grease cup and the slides or rails they sit on.
- 3
Replace damaged parts
Rusted, warped or missing trays and pans are replaced with parts that fit and line up correctly.
- 4
Check what grease has damaged
Grease overflow can damage burners, hoses, wiring and the cabinet. We look at all of it.
- 5
Test the path
We confirm grease will run from the firebox into the tray as designed.
A cleaning usually fixes it
Most grease problems we see aren't broken parts. They're years of grease that never got cleared. A deep cleaning resets the whole system, and our how often to clean guide explains how often yours probably needs it. If you'd rather not think about it, a maintenance plan puts it on a schedule. For details on what we use, see eco-friendly grill degreasers.
Grease tray questions
How often should I empty the grease tray?
Check it every few cooks, and empty it when it's about a third full. Heavy users may need to do it weekly in summer.
Can I use foil in the grease tray?
On many grills, yes, and it makes cleanup easier. Just don't block the firebox opening or any vents with foil.
Grease is dripping into my grill cabinet. Why?
Usually an overflowing tray, a rusted-through pan, or a tray that isn't lined up with the firebox opening.
Can a full grease tray cause a fire?
Yes. A full or overflowing tray close to the burners is one of the most common sources of grease fires.
How much does it cost to fix?
It depends on whether it needs cleaning, parts or both, and on the grill's brand and size. Send photos and we'll quote it.
