Why
Many plastic containers are made from polypropylene (PP, #5) or high-density polyethylene (HDPE, #2), which are typically dishwasher safe on the top rack. However, thin or low-quality plastics may warp or degrade in high heat, and some lids have seals that can fail. Always check the bottom of the container for a dishwasher-safe symbol.
How do you wash Plastic Food Storage Containers?
Place containers on the top rack away from the heating element. Avoid using the heated dry cycle to prevent warping. Hand washing is recommended for containers with tight seals or if the plastic is thin.
