Why
Most Tupperware lids are made of polyethylene or polypropylene, which can withstand typical dishwasher temperatures, but repeated exposure to high heat and harsh detergents can cause warping, cracking, or loss of seal. Some older or specialized lids may not be dishwasher safe.

Place lids on the top rack away from the heating element. For best longevity, hand wash with mild soap and warm water.
