Things You'll Need
Liquid dish soap
An oily film on your dishes is caused by greasy food. The dishes need a grease-cutting dish detergent to remove the film. Commercial detergents are available to safely remove oily residue, or you can use baking soda to naturally eliminate grease from the dishes. Baking soda is a gentle cleaning product that can be used to both clean and deodorize. It is available in the baking aisle of your local grocery.
Fill the sink with hot water, and pour 1 tsp. of dish-washing liquid or 2 tbsp. of baking soda into the water.
Scrape off loose food from the dishes with a fork into the garbage can. Place the dishes into the hot water, and leave them to soak for up to 30 minutes.
Scrub the dishes clean with a nonabrasive sponge.
Rinse the dishes with hot, running water, and dry them with a clean dish towel. Or, let the dishes air-dry in the dish rack.
