Why
Most Tupperware products are made from polypropylene or polyethylene, which can withstand typical dishwasher temperatures. However, some older or thin-walled items may warp or degrade over time, and the manufacturer recommends placing them on the top rack away from heating elements.
How do you wash Plastic Tupperware?
Place on the top rack of the dishwasher, away from the heating element. Avoid using the heated dry cycle to prevent warping.
