No, you should not use bleach on dishes before putting them in the dishwasher. Bleach is a harsh chemical that is not safe for direct contact with food surfaces and can be harmful if ingested. Using bleach on dishes can leave harmful residues that may contaminate the food and pose health risks.
Dishwashers are designed to clean and sanitize dishes effectively using hot water and detergent. They have specific compartments or dispensers for dishwasher-safe detergents, rinse aids, and sometimes, sanitizing agents. These commercial dishwasher detergents are formulated to remove food residues, grease, and bacteria while being safe for food-contact surfaces.
If you feel that your dishwasher is not sanitizing dishes adequately, check the following factors:
Water temperature: Make sure your dishwasher's water temperature is set to the recommended level, usually around 120-140°F (49-60°C), to ensure proper sanitation.
Detergent selection: Use a dishwasher detergent that is suitable for your dishwasher and water hardness level. Some detergents contain sanitizing agents to ensure proper cleaning and hygiene.
Rinse aid: Use a rinse aid in your dishwasher to improve drying and prevent water spots. Some rinse aids also have sanitizing properties.
Proper loading: Ensure that you load dishes properly, allowing water and detergent to reach all surfaces for effective cleaning.
Using bleach in the dishwasher or on dishes is not only unsafe but can also damage the dishwasher's internal components and compromise its performance over time. If you have concerns about the cleanliness or sanitation of your dishes, following the dishwasher manufacturer's guidelines and using appropriate dishwasher detergents and additives should be sufficient for effective cleaning and sanitizing.
