Is Tupperware dishwasher safe?
Sometimes — with care
Tupperware containers are generally dishwasher safe, but only on the top rack and away from the heating element.
Why
Most Tupperware is made of polypropylene or polyethylene, which can withstand typical dishwasher temperatures. However, high heat from the bottom rack or drying cycle can warp or damage the plastic, so top rack placement is recommended.
How to wash it
Place on the top rack of the dishwasher, away from the heating element. Avoid using the heated dry cycle; instead, air dry or hand wash for longevity.
