Keeping your kitchen clean is important for keeping it disinfected. To keep your sponges disinfected, wet them down and place them in the microwave on high for one minute each. Wash your kitchen towels frequently in hot water. Always wash your hands and take a clean kitchen cloth when wiping down surfaces, drying your hands, unloading the dishwasher or drying hand-washed dishes. Make sure that your towels are dry; wet towels are breeding places for bacteria.
Also, one of the primary causes of bacterial infestations in the kitchen is raw meat. Consider switching to a vegetarian diet to eliminate a significant amount of food-borne disease-causing bacteria. Use baking soda as a natural abrasive cleanser to remove baked-on dirt and other soils that are hard to remove. Taking these steps should make your kitchen a much cleaner, safer place for cooking and eating.
