Clean a countertop convection oven only after it’s unplugged and fully cool, using a damp cloth and mild soapy water.
For the full breakdown, see our best 3-in-1 Microwave Air Fryer Convection Oven guide.
Cleaning a countertop convection oven comes down to one rule: never rush while the unit is still warm. Most of these ovens — from compact Dash models to full-size KitchenAid and Oster units — share the same basic anatomy, and that makes the cleaning routine nearly identical across brands. The crumb tray, wire rack, and baking pan handle most of the mess, so a quick weekly wipe keeps the heating elements and interior free of baked-on grease.
What You Need Before You Start
Gather these items before touching the oven — it makes the whole job faster:
- A soft cloth or nonabrasive sponge
- Mild dish soap
- A bowl of warm water
- A plastic scouring pad (only for stubborn spots, where the manufacturer allows it)
- A dry towel for the final pass
Steel wool, metal scouring pads, and abrasive cleansers are off the table.
Start with the oven unplugged and completely cool. Cleaning a warm oven risks burns and can warp the interior surfaces, so wait the full time even if you’re in a hurry.
- Unplug the oven and let it cool completely.
- Pull out the crumb tray and shake the crumbs into the trash. Dash’s manual recommends doing this often — not just at deep-clean time.
- Remove the wire rack and baking pan. Wash them in hot, sudsy water, then rinse and dry.
- Wipe the interior with a cloth or sponge dampened with warm, soapy water.
- Wipe the exterior with a clean damp cloth and dry it thoroughly so no moisture sits on the controls.
- Let everything air-dry completely before sliding the rack and pan back in and plugging the oven in.
Cleaning Stubborn Burnt-On Food Safely
Baked-on grease happens to everyone, and the fix depends on your oven’s interior coating. For nonstick interiors, soak a cloth in warm water and lay it over the spot for a few minutes to soften the residue, then wipe gently. A plastic scouring pad works only if the manufacturer allows it —
What you should never do applies across every brand: don’t immerse the oven in water, don’t spray or hose water into the cavity, and don’t let water run into the heating elements or control panel.
| Cleaning Task | Safe Method | Don’t Do This |
|---|---|---|
| Interior cavity | Damp cloth with mild soapy water | Spraying water directly inside |
| Heavy spatter on nonstick | Nylon or polyester mesh pad, warm water | Steel wool or metal scouring pads |
| Wire rack and pan | Hand wash in hot sudsy water, or top dishwasher rack | Leaving them soaking for hours |
| Crumb tray | Shake out often; wipe with damp cloth | Letting crumbs bake on repeatedly |
| Exterior and controls | Clean damp cloth, then dry thoroughly | Allowing moisture to pool on knobs |
| Stubborn burnt residue | Plastic scouring pad where the manual allows | Abrasive cleansers of any kind |
