How to Clean a Ninja Woodfire Outdoor Grill

The OG700 and OG750 Series Ninja Woodfire Outdoor Grill combines an electric heating system with a removable grill grate, crisper basket, grease tray and pellet smoke box. Grease and food residue should be removed after the unit cools, but the powered base is not dishwasher-safe and the smoke box is not cleaned like a food-contact pan. Ninja's official FAQ says the pellet scoop is dishwasher-safe, while the unit base, grate, basket, grease tray, smoke box and temperature probe require the specified hand-care methods. Ninja says smoke-box cleaning is not normally required; if creosote becomes excessive, a wire brush may be used there. This guide covers OG700/OG750-family models and defers to the exact SKU manual for included accessories.

What you will need

  • The owner's guide for the exact OG700 or OG750-series SKU
  • Mild dish soap and warm water
  • Nonabrasive sponges and soft cloths
  • A nylon dish brush for the grate and basket
  • A plastic scraper for cooled grease residue
  • A dedicated wire brush for excess smoke-box creosote only
  • Clean towels
  • Heat-resistant waste container for cold pellets and ash

Step-by-step instructions

Step 1: Finish the cook and cool the grill

Turn the grill off, unplug it and keep the hood open after food is removed so the unit can cool. Wait until the grate, heating area, grease tray, smoke box and probe are completely cool. Never add water to hot grease, ash or an energized appliance.

Step 2: Remove cold pellets and residue

When everything is cold, remove the pellet scoop and discard spent pellets or loose ash according to local rules. Keep water out of the pellet feed and electrical areas. Pellets that have absorbed moisture can swell and should not be pushed deeper into the smoke system.

Step 3: Lift out food-contact accessories

Remove the grill grate and crisper basket using their normal lift points. Scrape loose cooked-on food into the trash with a plastic tool. Do not strike a coated surface or use an aggressive metal scraper. Confirm dishwasher eligibility in the exact manual rather than assuming every removable part can go in the machine.

Step 4: Hand-wash the grate and basket

Soak cooled removable food-contact pieces in warm soapy water as needed, then wash with a nonabrasive sponge or nylon brush. Rinse and dry. Avoid oven cleaner, steel wool and abrasive pads that can damage coatings. A second soak is safer than forceful scraping.

Step 5: Clean the grease tray by hand

Ninja directs owners to hand-wash the grease tray in warm soapy water. Dispose of cold grease in the trash rather than a sink, wipe heavy residue first, then wash, rinse and dry the tray. Clean the accessible tray channel without pouring water into the powered base.

Step 6: Handle the smoke box separately

Ninja says regular smoke-box cleaning is not required. If an excessive creosote layer develops, use a wire brush only inside the cool removable smoke-box area as directed, then remove loosened dry debris. Do not use that wire brush on coated grate surfaces and do not wash pellets into the unit.

Step 7: Wipe the lid and powered base

Use a soft cloth dampened with warm soapy water on accessible exterior and cool interior lid surfaces, then a clean damp cloth and dry towel. Do not immerse or hose the base, pour water over the heating element, or allow liquid into the control panel, cord, plug or sensor connections.

Step 8: Clean the temperature probe if included

After the probe cools, hand-wash only the food-contact stem with warm soapy water and a soft cloth, keeping the connector and wire dry unless the exact guide states otherwise. Do not place the probe in the dishwasher or submerge its connector. Dry before plugging it back in.

Step 9: Reassemble and protect outdoors

Confirm that the grate, basket, grease tray, smoke box, probe and base are dry. Reinstall the grease tray before the next cook and seat accessories correctly. Close the hood and use a compatible cover only after the unit is cool and dry. Store pellets sealed and protect the cord connection from weather.
