I have been hosting for almost two years, and in an effort to help guests find the "right pan" or things that are familiar or they will like to use, I offer a variety. I have found the new non-stick ceramic cookware to be better, showing fewer signs of wear and tear. Also, checking your pans for cleanliness is a must. This subtly encourages guests to care for our kitchen things as if they were theirs.
I have not had to "replace" any cookware yet (two years in). The only things that I have had to replace are missing items. Sometimes, things disappear or perhaps get broken. People cook in my three homes, and I want them to feel confident that everything they need is there.
I also provide a variety of cooking utensils, which helps keep non-stick pans looking better. The dishwasher is not great for some pots and pans, and because people are not at home, they tend to toss them into the dishwasher, which will shorten their lifespan. I am okay with that because I agree with the mindset that convenience is a priority while traveling. Even cooking should be perceived as easy for a great guest experience.
Everyone has their own point of view on what is acceptable for the non-stick surface. I always ask myself if I would be disappointed in these or whatever item is in question. If yes, it's time to replace whatever the item (sheets, pots, pans, decor, towels).
