Sippy Cups - Algae

[teacakes]

Not sure if this is the right forum.

I have noticed there is some algae on the sippy cups that my DD uses, even though I wash them every night.

Any suggestion on how to wash these properly or to prevent alage. They are the hard plastic ones (Tommee Tipee ones)

Thanks

Oh they are a nightmare, aren't they? Had the same problem myself - I just couldn't clean out the little holes. I ended up buying another one, then finally moved onto one that has a flexi-straw, which seems to clean really well.

dishwasher?

I bought some of these recently now my kids are old enough not to ne knocking over all the time.

Really pleased with them - ad think they are much better for teeth.

Robert Dyas sells them too (although more expensive I think)

Tks for the tips will give them a go!
