No I do sift all my pellets and then store them in buckets with sealed lids, try to keep all the dust out and pellets in best shape as possible. My last cook I was messing around and I know myself included hasn’t been impressed with the built in clean out tool, but during the cook I used it but pushed down pretty firmly on it so it teetered and it seems like it caused the wire brush to make a lot better contact with the grating at the fire pit as I had a considerable amount more ash in my clean out tray then I normally get when I just pull it back and fourth. ?
