What is the best house hold item to use while extinguishing a grease fire?

The best household item to use for extinguishing a grease fire is baking soda, as it can help smother the flames by cutting off the fire's oxygen supply. Alternatively, using a fire extinguisher rated for Class K fires (specifically designed for kitchen fires) is also effective. Avoid using water, as it can cause the grease to splatter and spread the fire. If the fire is large or uncontrollable, evacuate immediately and call emergency services.
