I only use my breast pump every now and then. When I've uses it, I rinse it with running water and leave it to drip dry...

I went to use it yesterday and it's got mould! The mould isn't actually where the milk travels through.

It's a medela mini electric. If you have one, or other medela similar, you'll know(hopefully) where I'm talking about.

Where the milk drips out into the bottle- if you take the valve off, the mould is up there, but in behind the plastic, so it doesn't actually come into contact with the mould.

How can I clean it out? The gap to get in there is too small for me to get in there with a (clean) dishcloth .

I have no idea how to clean it out, if I should use it (I haven't since discovering it), where I'd get a replacement, how much that would cost and a million other questions...

Any ideas?
