<<Disclaimer: Verify this information before applying it to your situation.>> Do you let other people eat glutenous food in your car? My two older kids eat gluten like McDonald's and my youngest son and I do not. Do the gluten crumbs end up contaminating the car?? Do we end up breathing it? I'm afraid my youngest will inadvertently touch some crumbs or molecules of it and end up with a reaction. Thank you, Mary Holford San Jose, CA
