Barbara,
I love the idea of using peroxide and baking soda for bathroom fixtures and tile! Thanks for that tip!
To answer some of your questions (and please understand this is just MY experience and preference, not advice):
In the kitchen, most of my utensils are metal, but I do use plastic cutting boards. We have both cloth hand towels and paper towels. In regard to cleaning countertops, etc. I generally use a homemade vinegar spray and wipe with paper towels. We do have a dishwasher, but rarely use it. I generally prefer to wash by hand and air dry in a dish drainer.
We replace bath towels every few days, and just wash and dry them like we would any other kind of laundry. (Washing machine and dryer.) I don’t line or air dry our laundry because I don’t like the way it makes things feel stiff – hah! Also, I’ve never disinfected my washer or dishwasher…
I’m learning that advice given to families today is very different from advice my parents were given when my sisters and I were young. There are so many more “rules” and guidelines now! For instance, I would have NEVER have though about the dishwasher being potentially unsafe for little ones with CF. With increased knowledge and information, there comes a lot more advice and guidelines. I find myself learning new things from parents of children with CF all the time! In ways, you are more educated and up-to-date than us older CF folks!
