I recently bought the Ironwood 650. Ashes everywhere grates and food too. I seasoned it, then did the 3-2-1 ribs. The clean grill indicator showed. I noticed about 1/4 to 3/8 of inch thick ashes and ash dust all over the sides and grates. I have done three cooks total and seems that any cooks over 6 hours generates a lot of ash. Traeger is trying to tell me this a normal??? My old Costco Traeger 22 inch never generated this much ash and it never was above the drip tray. This is after a 9 hour pork shoulder.
