@lyndsie94 well I'm not sure bc i don't have a steam asterisks sterilizer.😣 but try and add some baking soda to the water, and let it sit over night. if you can I'm not sure how they work lol or just try and run it through

update: lemon juice does not work!! it pretty much crystallizes on the burner. and it's pure juice.
@rosalinasmami I haven't had it but a day so I haven't had time to play with it much. I just bought it from someone and it smells weird. should I put that in and let it run or just wash it with it?

have you tried using baking soda with the soap and water?

I have a steam sterilizer so that I don't have to boil them all the time. and I keep washing it wish soap and water, but it just still stinks

hot water with sop or boil the bottle in a pot of water with sop or limon juice
