Whether you can put plastic mixing bowls in the dishwasher depends on the specific type of plastic and the manufacturer's guidelines. Many modern plastic mixing bowls are dishwasher-safe, but some may not be suitable for dishwasher use. Here are some general guidelines to help you decide:
Check the label or packaging: The manufacturer usually provides information on whether the plastic mixing bowl is dishwasher-safe. Look for any symbols or instructions related to dishwasher use on the bottom or the packaging.
Look for temperature restrictions: Some plastic materials can warp or deform at high temperatures, which are typical in dishwasher cycles. If the plastic mixing bowl is not rated for high heat, it's best to avoid using the dishwasher.
Avoid using the dishwasher for older or worn-out plastic bowls: Over time, plastic can become more susceptible to heat and may not hold up well in the dishwasher. If your plastic mixing bowl is old or shows signs of wear, it's safer to wash it by hand.
Consider the dishwasher's settings: Some dishwashers have different settings, such as gentle or low-temperature cycles, which may be more suitable for washing plastic items. If your dishwasher has these options, you can try using them for plastic mixing bowls.
Hand wash when in doubt: If you are unsure about the dishwasher safety of your plastic mixing bowl, it's best to err on the side of caution and wash it by hand with mild dish soap and warm water.
Keep in mind that even if a plastic mixing bowl is labeled as dishwasher-safe, repeated exposure to the high heat and strong detergents of the dishwasher may cause it to degrade faster over time. If you want to prolong the life of your plastic mixing bowls, consider hand washing them instead.
