Why
Most plastic containers are made from polypropylene (PP) or similar plastics that can withstand dishwasher heat, but high temperatures and harsh detergents may cause warping, cracking, or clouding over time. Additionally, the top rack is safer than the bottom rack to avoid direct heat exposure.

Place containers on the top rack of the dishwasher, away from the heating element. For longer life, hand wash with mild detergent and avoid abrasive scrubbers.
