Bleach can be washed in any dishwasher with a plastic interior or labeled “bleach safe” by the manufacturer. Bleach is dishwasher safe unless the interior is lined with stainless steel or has sensitive parts covered with this material. If you are 100% sure that your dishwasher is covered with plastic and has plastic parts (usually with less expensive models), then bleach.
Powdered bleach should only be used for occasional cleaning, about once a month, and should never be used in place of your regular dishwasher detergent for washing dishes, as it can damage the inside of the dishwasher.
To add the bleach, use a dishwasher safe and bleach container. It is not necessary to start a drying cycle, stop the dishwasher at the end of the cycle. Simply load the dishwasher as usual, pour 1/4 cup bleach into the bottom, add your regular detergent to the dispenser and continue working as usual.
If your dishwasher is all plastic, you can definitely use bleach. This is why it is not recommended to use ordinary household bleach in stainless steel dishwashers. Although bleach is great for killing bacteria, mold and mildew, it may damage your dishwasher if it is stainless steel or has stainless steel parts inside. Adding bleach to the dishwasher will damage the rubber seal on the door of the machine.
When cleaning a dishwasher or anything else, never mix vinegar with bleach. And don’t use vinegar bleach-this combination can produce potentially deadly chlorine. If you don’t have baking soda or white vinegar, you can also use bleach to clean the equipment.
