The best way to remove aluminum foil facing from food after use is to carefully lift the edges of the foil with a pair of tongs or a fork, ensuring not to touch the food directly with your hands. Gently pull the foil away from the food, starting from one corner and working your way around. If the foil is stuck, use a butter knife or a spatula to gently separate it from the food. Be cautious not to tear the foil, as this can create sharp edges and make removal more difficult. Always dispose of the used foil properly in a trash receptacle.
