You didn’t miss anything. She said she never uses soap because she boils every day. I agree with you, the soap breaks up the biofilm on the equipment. I rinse and soak with Dawn free and clear unscented then boil. I don’t agree with not covering the equipment for drying either. I take mine from boiling into the Bololo sterilizer/dryer and run the full cycle with the cover on. I do four sets and leave it covered removing as needed until time to sterilize them all again.
Not everyone does it the same way, but this is what I settled on after much research and advice.
