I'm still pretty new at this, but I have gotten pretty quick with rolling up newspapers and stuffing them under the chimney. I roll up the newspaper somewhat tight and it burns the perfect amount of time. I then set the chimney on my lower grate that holds the charcoal or on my other grill, which catches all the newspaper ash. Once you dump the charcoal onto the grill itself, there really isn't any newspaper ash left. It has worked for me in my short time doing this, but I expect I'll get bored eventually and start trying unconventional methods!
