That’s a good way to go especially if you’re concerned about accidental burns while cleaning it. However I’ve come to prefer the damp sponge while the grill is hot. It is flat out the easiest cleanup method I’ve ever seen in anything like this. No matter how you clean it up, the grill itself is a Godsend when it comes to eating with less grease and fat

BETTER WAY TO CLEAN GRILL:

Unplug & let cool about 10 minutes with cover down.
Moisten 2 paper towels & wring out excess.
Fold to fit inside surface, put inside grill & close cover.
After you wash the dishes wipe off surfaces. The steam
generated while the cover was closed softens the hardened
food & makes cleanup real easy. Then you just throw the
paper towels away.
