Here's a tip for our MAK owners who have the 2 QT. grease drawers: purchase some of the foil loaf pans. (I buy 3 packs for $1.98 at Wal-Mart). Bend up the lip of the pan. Then fit it inside the grease drawer. It will catch your ash and grease and help keep the door clean.
Also---keep your empty pellet bags. When you're ready to throw away your nearly filled foil loaf pan from the grease drawer, put it into the empty pellet bag and secure it with a twist-tie. It will help keep the grease from spreading all over the inside of your garbage can.
