I mean logically the kind of shit that grows on your dishes isn’t much better for you than the literal shit that a toilet brush would scrub out of your toilet bowl. They both contain a lot of the same bacteria, you wouldn’t be much better off licking an old used plate that has been sitting in a moist environment for a few days before you put the dishwasher on than you would be from licking a toilet brush. Well made dishwashers are designed to vigorously wash and, with the right settings and detergent, sanitize everything inside them so that they are safe to eat off of. Heck the machines they use to sanitize surgical equipment are essentially fancy dishwashers. But emotionally I couldn’t do it. Even if I used the best dishwasher known to man and rewashed everything multiple times, I just wouldn’t be able to get over that mental hurdle.
