I'm thinking I'm doing something bad/unhealthy because we only wash DS's sippy 2-3 times a week. For the most part, he only has water in it...only sometimes some diluted juice. We're in the habit of just sticking it in the fridge in the evening and then getting it out the next day when we need it again...without washing in between. I've noticed, though, some dark spots (mildew?) on some of the interior pieces (we use a Born Free cup) that are appearing after a day or two. So, this seems to point to "wash very thoroughly every day." Is this what y'all do?

Anyway, the cup parts get washed in the dishwasher, all other pieces get washed by hand in hot hot hot water. I have been known to re-use her water sippies for an extra day, I don't think that's bad at all.

Ours goes in the dishwasher we probably go through 2 or 3 a day
Milk is put in a proper glass & ds doesn't generally get juice.
Surviving sleep deprivation one day at a time with dd (Oct '11) & ds (Oct '08).
If I give a sippy of juice or milk, I either hand wash it with soapy water or put it in the dishwasher the same day.
At the end of the day, I remove the straw pieces and stick them inside the cup. I squirt some dish soap inside and fill with super hot water and let it soak. Then I hand wash the straw and rinse well. Then I use a bottle brush cleaner for the cup part-done! We're silly here and rarely use our dishwasher. We should use it more!
I'd think if you are just using them with water and juice and putting in the fridge in between, they would be okay... except that if saliva mixes with the liquid, would it cause bacteria to grow? I've definitely put a cup of milk into the fridge if only a sip or two was taken, and DS doesn't want anymore - but most if the time he chugs it all in seconds (and wants more).

I would wash it every day.

Her other KK which lives in her bed gets a thorough rinsing every second night or so because it gets kinda slimy because the water is touching the valve all the time and it grosses me out.
This is so embarassing. I can't believe I am admitting how disgusting I am!

They get 2 cups a day--one for milk, one for juice. At the end of the day, it is dumped and washed in the dishwasher. Sometimes I will keep the milk one in the fridge if they didn't finish it off at night, and then they can drink it in the morning and then it goes in the sink as soon as empty.
We use Siggs when out and they get the same treatment.
OP, the black bits you see are probably fungi or bacteria. Since both of these are microscopic, there must be millions of them for you to even see them, so eeeeeeeew.

They straws are SO hard to get clean, I notice black stuff in them which worries me. I end up using a q-tip to try and clean them. He has his morning milk in his sippy which i think is the culprit for the black nastiness
I wash the cups every day with soap and hot water. I put them in the dishwasher maybe 2-3 times a week, depending.
My rule of thumb is simple -- I think to myself, if I fill this w/water again, would *I* drink from it? Once, I sipped from one that I didn't wash, just rinsed and refilled, and the water tasted fishy - probably had some mildew or algae. Gross. So now I always wash w/hot water & soap.
