Tupperware? No. That stuff is never fully clean. Even 5 cycles in the dishwasher wouldn’t fully clean it, IMHOCDO.
If it were stainless steel, and boiled for ten minutes, maybe.
I don’t really use any Tupperware or similar products any more. I get the disposable gladware type things. I do reuse them a few times before they end up in my art supplies.
Sure, but those of us who don’t follow the convention of using our kitchenware for food and use it for pooing in may not follow other conventions, like washing our hands after doing a poo.
