It is generally not recommended to use bleach on dishes before putting them in the dishwasher. Bleach is a strong chemical that is primarily used for disinfecting and sanitizing surfaces, especially in the context of cleaning bathrooms, floors, and other non-food contact areas.
Here's why you should avoid using bleach on dishes before putting them in the dishwasher:
Residue and Safety Concerns: Bleach can leave a harmful residue on dishes, even when diluted, which can be toxic if ingested. Dishwashers are designed to clean dishes effectively using detergent, water, and high temperatures, so adding bleach can interfere with the dishwasher's normal cleaning process and may lead to undesirable results.
Potential Damage to Dishwasher: Bleach is a corrosive substance and can cause damage to the internal components of the dishwasher if used inappropriately. Dishwashers are not designed to handle bleach directly, and introducing it into the dishwasher could lead to malfunction or premature wear and tear.
Chemical Reactions: Mixing bleach with any leftover detergent or soap residue on the dishes can cause chemical reactions that produce harmful fumes. It's essential to avoid combining bleach with other cleaning products to prevent the release of toxic gases.
To ensure your dishes are properly cleaned and sanitized, it's best to follow these guidelines:
Pre-rinse Dishes: Before loading the dishes into the dishwasher, scrape off any large food particles, but avoid pre-washing with soap or bleach. Modern dishwashers are designed to handle dirty dishes without the need for extensive pre-rinsing.
Use Dishwasher Detergent: Add the appropriate amount of dishwasher detergent according to the manufacturer's instructions. Dishwasher detergents are formulated to work effectively with the dishwasher's cleaning cycle, ensuring optimal cleaning and sanitizing.
Select the Right Wash Cycle: Depending on the level of soil and the type of dishes, select the appropriate wash cycle on the dishwasher for best results.
Maintain and Clean the Dishwasher: Regularly clean and maintain your dishwasher according to the manufacturer's recommendations to ensure it operates at its best.
If you're looking to sanitize dishes further, some dishwashers have a high-temperature wash or a sanitize cycle option that uses extremely hot water to kill bacteria and germs effectively. If you're concerned about the sanitization process, consult your dishwasher's user manual or consider using a dishwasher-safe sanitizing solution or tablet designed for use in dishwashers.
