To determine if plastic is dishwasher safe, you can look for specific symbols, markings, or labels on the plastic item itself or its packaging. Here are some common indicators to check:
Check for a dishwasher-safe symbol: Look for a symbol on the plastic item that resembles a dishwasher or a dish with water droplets. It usually indicates that the item is safe to be washed in a dishwasher.
Read the packaging or label: If you still have the original packaging or any accompanying labels, check for information regarding dishwasher safety. Manufacturers often provide instructions or warnings about the dishwasher suitability of their products.
Inspect for material type: Different types of plastics have varying degrees of tolerance to high temperatures and dishwasher cycles. Plastics with a higher heat resistance, such as polypropylene (PP) and polyethylene (PE), are generally more likely to be dishwasher safe. On the other hand, plastics like polyvinyl chloride (PVC) and polystyrene (PS) are less heat-resistant and may not be suitable for dishwashers.
Look for "dishwasher safe" wording: Some plastic items may explicitly state "dishwasher safe" on the bottom or side of the item.
Check the manufacturer's website: If you're unsure about the dishwasher safety of a specific plastic item, visit the manufacturer's website for more information. They may provide care instructions and guidelines for their products.
However, it's essential to note that even if a plastic item is labeled as dishwasher safe, repeated dishwasher use may cause it to degrade over time. High heat and strong dishwasher detergents can weaken plastic materials, leading to warping, discoloration, or a reduced lifespan. For items that are valuable or have sentimental value, it's often safer to wash them by hand to preserve their condition.
If you can't find any information about the dishwasher safety of a plastic item or you're unsure, it's best to err on the side of caution and hand wash it instead.
