How to Clean and Re-Season a Traeger Flatrock Griddle
A Traeger Flatrock cooktop is maintained while hot, but its grease keg and exterior are handled only after cooling. Traeger recommends scraping the cooktop after each cook, using a little water for stubborn residue if necessary, then applying a thin coat of conditioner or high-smoke-point oil and heating until smoking ends. Cleaner that is safe on the cooled grill body must not be used on the cooking surface. Separating those hot and cold jobs protects the seasoning, reduces rust, and keeps hot grease from becoming a burn hazard.

Step-by-step instructions
Step 1: Plan the clean for the end of the cook
Traeger recommends cleaning after each cook while the griddle is still hot because residue releases more easily. Keep children and pets away, use long tools, and never touch the cooktop, grease chute, or hot grease. If the surface has cooled, heat it on medium for about 10 minutes as Traeger directs rather than attacking cold residue with excessive force.
Step 2: Scrape residue toward the grease chute
Hold the scraper at a controlled angle and move food particles and grease across the full cooktop into the chute. Use overlapping passes, including the edges and sidewalls, without gouging the surface. For stuck bits, let them char briefly and scrape again. A small amount of water can loosen stubborn residue, but stand back from steam and use only enough to assist scraping.
Step 3: Remove water and loose debris
Guide all softened material toward the chute and wipe away the remaining film with tongs holding a clean towel. Do not leave puddles to air-dry on the iron. Never apply soap, degreaser, Traeger All Natural Cleaner, or another cleaning solution to the cooktop; Traeger explicitly reserves its exterior cleaner for the cooled body.
Step 4: Apply a thin protective oil layer
While the cooktop remains hot, add a thin layer of Traeger conditioner or canola, grapeseed, or flax oil. Traeger's support instructions describe roughly two to three tablespoons for the surface. Use tongs and a clean towel to spread an even film over the cooktop, sidewalls, and edges. More oil is not better; thick or sticky patches indicate excess.
Step 5: Heat until smoking finishes
Let the thin coat heat until smoking ends, which completes the post-cook mini-seasoning and helps guard against rust. Stay with the grill and maintain safe ventilation. When finished, turn every burner knob to OFF and close the propane tank valve. Do not close the lid while the Flatrock is operating or hot.
Step 6: Let the grill and grease cool completely
Wait until the cooktop, body, chute, and grease keg are cool. Traeger warns never to remove the grease keg while the grill is hot. Once cool, discard the liner and contents appropriately and install a fresh liner when needed. Inspect the grease chute for buildup; remove and wash it only as the model instructions show. Traeger identifies the removable chute as dishwasher safe.
Step 7: Wipe the cooled exterior
Use a cloth and Traeger All Natural Cleaner, or another manufacturer-compatible natural cleaner, on messy exterior body surfaces only after they have cooled. Apply cleaner to the cloth for better control and keep it off the seasoned cooktop, burner openings, regulator, hose, ignition parts, and labels. Dry the body so water does not collect at seams.
Step 8: Treat rust only when necessary
For surface rust, Traeger starts with a nonabrasive or green scouring pad and water. If that cannot remove it, the manufacturer permits 220-grit sandpaper on the affected cooktop area. Wipe away all rust residue and towel the surface completely dry; do not heat puddled water to evaporate it. Re-season the repaired cooktop before cooking.
Step 9: Store the Flatrock dry and protected
After the grill is fully cool, close the lid and install a fitted cover. Keep the propane valve closed and follow local cylinder-storage rules. Traeger advises warmer storage when conditions fall below minus 20 degrees Fahrenheit, or minus 29 Celsius. Before the next cook, inspect the hose, regulator, burner flame, and grease path rather than using a damaged or obstructed grill.
