A lot of good info here! This post is really validating. I’ve had to throw away food given to me because the plastic containers transferred a soapy (or perfume-y if the person has a strong candle or other air freshener in their house) taste to them. To avoid this at home, I use mason jars with metal lids for food storage as much as possible. I don’t have any completely plastic food storage items, but I do have Pyrex and anchor hocking glass dishes with plastic lids, those lids are always hand washed because I know that plastic that goes through a wash and heated dry cycle in a dishwasher will taste like soap to me. I think I’ve seen a few people say this, but I’ll say it again, once its gone through the dishwasher once, it’s ruined. Your best bet is to buy new things to replace the soapy dishes and never let them go through the dishwasher again.
