How do I get the sour milk smell out of sippy cups?

With winter here (the heat is on) and Gabby (9 months) keeping us busy and Ally (3) throwing her cups in the sink and forgetting to tell us she is done with her mik, a lot of her cup have a sour smell. What is a good way to get rid of it? I have tried leaving soapy water overnight and that didn't work and I have tried bleach with no luck on that either. We can't afford to just throw them away (my mother's suggestion). I guess this is the right category to put a cleaning question. LOL!

Thanks!

  • Try scrubbing them with a paste made from lemon juice and baking soda, both are natural deodorizers. I would probably scrub them good and let the paste kind sit on the cup overnight before rinsing it out.

  • Dawn always works for me, you will need a good squirt for each cup, get the water really hot and it will take the smell right out. I like the Orange antibacterial dawn best, it doesn't leave a funky taste behind on the plastic cups like other dish soaps. My son will throw his cups in the back of my truck and I always find them on grocery day.. a week later......or he hides them under my bed! Blech!

  • i know when sippies used to have the white plastic piece with the spring in them, my mom had trouble with getting old milk out of the spring part. she called the company that made them and they told her to use a denture cleaning tablet. if you know somebody with dentures and can get a few, i'd give it a try, but i wouldn't buy a box just to try it.

  • Have you tried boiling them? Could work. I actually took mine to my sisters once because she has a dishwasher and she and I both agree that it gets the cups cleaner than hand washing (especially the inserts)...so take them somewhere with a dishwasher, silly as it seems...lol

  • Wash them with lots of vinegar in the water. That will get rid of the smell. I do it all the time. First I boil them, then I let them soak in vinegar, then I wash them out with soap and water. Good luck.

  • Try boiling them for a few minute. Take all the peices apart and put them in boiling water for a few minutes.

  • Distilled viegar. Soak them for a few hours in vinager and water, then in hot water. Wash and repeat oif needed. Boiling is not going to help with the smell. Vinegar should though. If not, then I'd have to agree you need to throw away. Good luck. I hated finding those "special sippy's"...grrr EW!

  • A lot of the cups can't be boiled, the three dollar package of cups my daughter tears up, these cups she has were three dollars each so I can't throw them out. iam about to go try the baking soda (don't have any lemon, i don't think) and I have vinigar.
