In most cases, yes, a toaster oven tray can go in a dishwasher. Toaster oven trays are typically made of materials like stainless steel or aluminum, which are dishwasher-safe and can withstand the dishwasher's cleaning process.
However, it's essential to check the manufacturer's instructions and guidelines for your specific toaster oven and tray to ensure they are dishwasher-safe. Some toaster oven trays may have a non-stick coating, and prolonged exposure to the high heat and detergent in a dishwasher can potentially damage the coating. In such cases, it's better to hand wash the tray to maintain its non-stick properties.
If your toaster oven tray is dishwasher-safe, make sure to remove any large food particles or residue before placing it in the dishwasher. This will help prevent clogging and ensure more effective cleaning.
If you're unsure about whether your toaster oven tray is dishwasher-safe or how to clean it properly, refer to the instruction manual or contact the manufacturer for specific guidance.
