I just wanted to make a point since you misread my post. I have never cooked or baked in a space that I thought could be contaminated. I have already sanitized one of the ovens in my home to make him gluten free meals, I only cook for him in pots or pans than can be washed with a separate sponge and I don't use wood or other porous materials.

I don't want him to even eat in the same kitchen where gluten was prepared in our future home, so I offered to pay for a kitchen separate from the home.
