Whether I am using a $35 charcoal grill or a recently bought Master Forge $200 grill, I would line the charcoal pan with heavy duty aluminum foil. The day after I use the grill is when I would just fold up the aluminum foil liner including the charcoal ashes for disposal. After a thorough scrub and wash of the grates and wipedown of the entire grill would I reline it with new foil and it is ready to use anytime in the future.
The $35 grill lasted me 15 years todate and could still be used if I wanted to. However, with the upgrade, its rightful place is next to the MF with the chimney starter as its new friend.
