I have a S/S Stone that I have been using for over 12 years. Attached to it is a 5' tubing that I slip on to a medical o2 tank. After use I wash in PBW and before use I soak in Iodine solution. Every once in a while, when I think about it, I will boil it . I have not had an infection but............................ What are you doing that I might change my habits?
