Hubby left a few of my baby's bottles in his car wit a little formula in them for a few days. I cleaned them out and ran them through the dishwasher and sterilized them, but they still have that lingering sour milk smell. How do I get rid of it? I'm afraid to use bleach. These are the hard plastic Soothie bottles.
I know you're afraid to use bleach but its very safe if you do it correctly. What I always did was dilute the bleach and let the bottles soak in it for an hour if they weren't too bad, if they had a horrible smell I would let them soak overnight. Run them through the dishwasher and then sterilize them afterwards.
exactly what Punchy said! The vinegar should take care of it. I run a coffee cup filled with vinegar through my dishwasher once a week to get rid of the sour milk smell in my daughters sippy cups.
Try cleaning them with vinegar and then washing them with dishwashing liquid after. I've done this before too. My son used to throw his bottles in the car floor when he was done. Sometimes I would forget and then find them days later under my seat.
Let them sit with some vinegar in them. Then run them through the dishwasher again and see if that helps. You can also try making a paste of baking soda and water and letting them sit for a few hours, then run them through the dishwasher.
