yes, my world is small... but does anyone know how to clean tommee tippee tops?

[ilovemydog]

Am I the only one whose toddler's Tommee Tippee (sippy cup) top has what looks like mildew I have tried soaking them, scrubbing with a toothbrush etc...

i used to clean ds's woth a cotton bud

I put dds in a bowl with diluted bleach, soak over night and then put through a hot dishwasher cycle.

Oooo I have never experienced this problem; I try to rinse mine out after use and then put them in the dishwasher....Oh gawd, maybe I'm too slatternly to have noticed mould on the cups
