I wait until my Bullet is cooled down after roasting, but still has some thermal retention…should be warm to the touch but not burning. I remove the rear chaff collector next. Afterwards, I take a Cafeza solution soaked rag and push it thru the back upper exhaust tunnel (i dont know its formal name) and all the way to the front by the charge tunnel and it works amazing. Ill take pics next time I do this.
