It appears that the dishwasher knows no limits. As reported in Food & Wine magazine, the Tik Tok trend of putting lettuce, celery, and other produce in a dishwasher to wash them is a really bad idea. Dishwashers can harbor residual chemicals that could prove harmful if eaten. Food & Wine says these items, too, should never go in a dishwasher: cast iron pans, enamel Dutch ovens, wooden spoons, cheese graters, and insulated mugs. As for #B, I personally think you’ll ruin your dishwasher if you put takeout containers in it. But I do know #C, a woman who regularly washes her son’s Legos in the dishwasher.
