We do not have a specific list of plastics that are dishwasher safe. The following is the information that we were able to find on our products. It is up to the manufacture to tell us if a particular item is dishwasher safe.

Polycarbonate is sometimes weakened by repeated cycles in a dishwasher and stress cracks are one of the indicators of this. Polycarbonate may by some manufactures be considered dishwasher safe and damage resulting from washing may vary depending on temperature and location in dishwasher.

Every source that we looked at indicated that Polypropylene, HDPE, and LDPE are top rack safe. Please note that LDPE does have a somewhat low temperature rating. Temperatures above the maximum recommended temperature may cause warping or distortion of plastic. These are the three most common plastics used for food storage containers and lids.

All StorPlus™ and Traex® food storage containers that we offer are dishwasher safe. We have tried in most cases to include this information in the description on food containers.
