Cousin,
How I foil the FEC for easy cleanup. You probably are already familiar with this. I use heavy duty foil and line the floor of the FEC, poking my finger through the openings at the bottom front drain and the drain at the right front. I also place foil over the piece that slants, a piece across the fat catcher, the skinny piece that fits into the floor(shaped like an upside down L) poking a hole into the channel. The channel opening is easily cleaned out using a bottle brush. We use a disposable aluminum pan as the drain pain. At the end of a cook, we strip out the aluminum, put it all in the disposable pan, throw it out, vaccuum, reline with aluminum, and we're set for the next cook.
Good cooking!
Peggy
P.S. We clean it all out when necessary using lemon juice and a water rinse.
