I bought the squeezie because I read it could be boiled, but am not sure where I saw it. I boiled them 10” 1-2x/week until I got the Bololo. It was fine. : )

I just calledNeilMed customer service and he said they do not recommend boiling. He said microwaving and baby bottle sterilizers are fine. He recommended just washing with soapy water. I asked why it’s ok for the bottle sterilizers and not a pot of water since temp is about same. He said they’re afraid bottle will lose shape and pressure.

I have 2 thoughts: one is that I’m not sure those answering customer service are that familiar with equipment.
The other is that perhaps the pan bottom might get hotter than the water. I used a little silicone hot pad in bottom when I boiled the thinner older bottle, which the customer service folks had said could be boiled 5 min, but not 10.
