I don't remember, I should listen to that part again. Your method should kill NTM. 1/week, I boil pieces in distilled water for 10 minutes, but daily I soak in Dawn, rinse and microwave in a micro-steam bag. The biggest take away for me, was that for MAC washing and disinfecting-use anti-microbial dawn and soak for 30 minutes. Kills MAC (or at least significantly reduces it.). 5% Vinegar and 70% ethanol both were good for MAB and MAC. I also let dry on paper towels and cover with paper towels.

I think I will add a 5% white vinegar soak 1/week. That will keep everything scale free and disinfect at the same time. I like the glass pot! I just ordered silicon matts (got that idea from Sue) to put in pan before boiling. I need a better pan and colander. Also, in the future, I will be buying anti-microbial Dawn.
