Can You Put Tupperware In The Microwave With The Lid On?
It is generally not recommended to put Tupperware with the lid on in the microwave as the buildup of steam can cause the container to warp or melt. It is safer to remove the lid or use microwave-safe plastic wrap to cover the container to prevent splatters. It is also important to check the bottom of the container to ensure it is labeled as microwave-safe.
