No, it is not recommended to put bleach in the rinse dispenser of your dishwasher. Bleach is a strong chemical that can be corrosive and may damage the internal components of your dishwasher. Additionally, using bleach in the dishwasher can potentially release harmful fumes and pose a health risk.
To sanitize your dishes, it's best to use the dishwasher's built-in sanitizing cycle or high-temperature settings if available. These cycles typically use hot water and high temperatures to kill bacteria and sanitize your dishes effectively. If your dishwasher doesn't have a specific sanitizing cycle, you can use a dishwasher detergent that contains a sanitizing agent.
If you're concerned about the cleanliness of your dishes, you can also consider pre-rinsing them before loading them into the dishwasher and regularly cleaning and maintaining your dishwasher according to the manufacturer's instructions.
