Clean burned-on food spatters with dry baking soda

Wet the areas and sprinkling liberally with dry baking soda, or by wiping on enough baking soda paste (3 parts soda to 1 part water) to cover the spatters. Leave for a while before wiping away. If some stubborn residues remain, repeat the process. Be sure that the paste is wet enough to soak into the burned-on patters.
