@lilianna, thank you for your clarification. I have been rinsing under very hot water, soaking in dawn and hot water, and then rinsing that in a bowl of distilled water because our water is so hard. All this before boiling for 10 minutes in spring water, again because of the water hardness. I use a lot of water, and it adds up. Also many paper towels!!!
Is your two part sterilizer the Philips Avent? Do you like it, and is it reliable? Do you find that it dries well, or do you have to put it through 2 drying cycles? I also found that my Vortex holding chamber for my Levalbuterol canister can be placed in a steam sterilizer (electric, not microwave, since it has metal). I had been soaking it in Dawn and then placing it in alcohol for a time and rinsing it. Just trying to finally streamline everything to where it is effective but also practical and not cost-prohibitive. Thank you again so much.
