@tte If you have been counseled to use fragrance free, non-antibacterial detergent and are comfortable with that, then that's your answer. Your method of using boiled distilled water sounds spot on. Dish washing detergents contain surfactants, Dawn and others, which bust biofilms on our plastic gear. It's in these biofilms where NTM and pseudomonas and other pathogens hide and grow. Your BBS will then dry your equipment thoroughly halting further development of biofilms.

There's a particularly good up-to-date video presentation by Dr. Honda on this topic that anyone who is questioning their current methods of cleaning and sterilizing would benefit from watching. https://www.youtube.com/watch

What you decide to do depends on your disease state, comfort level, and risk tolerance. You will read here and other places varying degrees of methods and routines. Until there is a testing kit for home use which can test the adequacy of each method, we rely on experts in the field like Dr. Joe Falkinham and Dr Honda to guide us.

And remember to keep up with airway clearance as it's the mainstay of treatment for bronchiectasis!

@tte I still wonder why I have to soak in soapy water if I IMMEDIATELY immerse in boiling distilled water and boil for the recommended 10 minutes and an additional minute for every 1000 feet of elevation. I will write to nationally famous biofilm expert, Dr Falkinham and then I will post his answer.
