"The twenty-first century has different standards regarding the cleanliness of clothing than most previous time periods," Steve explained as students arrived at the fourth and final niche, set up like a laundry room. "This is because of the mechanization of washing clothes, via the washing machine and dryer." He proceeded to explain how these worked on a basic level before moving on to explain which fabrics could not be washed in them and would still require hand washing or a trip to a dry cleaner, "which is another story for another class. Modern clothing will have care tags inside, and you can just follow the instructions on them to wash your clothes, but for clothing without care tags, the best rule is to keep dark colors together and light colors together, and wash whites separately. There are baskets of laundry for you to sort through and try out with the machines, and remember, it's all fake, so you're not really digging through dirty laundry."
