Thanks for pointing this out. I noticed it too on the slide that appears at 21:04 in the presentation, and was wondering if we should change our practices for my sister, who has Bronchiectasis and NTM. For nebulizer cup parts, we have been doing 10 mins. soak in sudsy regular Dawn/water then rinse, and run them through a sterilizing and drying cycle in the Philips baby bottle sterilizer. For my sister's Aerobika, we use a regular Dawn soak, then rinse and air dry daily, but also put this through sterilizer about once a week.

We're using regular Dawn for cleaning BiPAP mask pieces (which don't get otherwise sterilized). A concern for BiPAP parts would be the scents of the antibacterial Dawn (although of course, Dawn already has a scent), but also, as you mention, lotion or softener ingredients that might affect the silicone parts...

I hope you will post whatever additional information you obtain from the medical sources! Thanks!
