Sippy cups smell like sour milk... should I throw them out?

My son has a few sippy cups and some smell like sour milk. The cups are clean just came out of the dishwisher. My question is should I get rid of them and buy new sippy cups? Should I use something special to wash them in? Right now they are soacking in warm, soapy water but I am not sure if that is going to do the trick or not.

  • try boiling them first. If that doesn't work then get new ones if you want.

  • I get all the sippies and all their parts and boil them in a pan of water on the stove for about 8-10 minutes every week - keeps them clean and smelling fresh.

  • it depends on the age of you child you could start switching to big people cups and not sippy, they say you can place sippy cups in bleach but wash them out good

  • put vinager in the dishwasher & run them through again.

  • When my son's started to smell, I would soak them in a sink full of hot water and about a 1/4 of bleach. That usually got rid of the smell. Just make sure you wash them a couple times before you use them again.

  • I had a few like that. . . I pitched them and started switching the sippies to the take & toss disposables.  I figure I can use the same cups after I transition to big boy cups.
