Greasy bottle teats with cows milk?

[Zil131]

Does anybody else find it hard to get bottle teats sparklingly clean when using full cream cows milk (from milkman - so has cream top).
I'm sure that with EBM / formula milk a bowl of hot soapy water and a scrub with the bottle brush did it, now they look permanetly cloudy / greasy.
I know DS should be 'moving to a cup', but it's just not worth the tantrum!!
Or am I just a dirty slattern who can't wash up properly??

I'm clearly one too!! I had this problem also and I ended up putting them in a bag meant for washing tights and popping them in the dishwasher. If you don't have a dishwasher (and I don't really like putting mine in so don't do it very often) is leave them to soak in very hot water with fairy liquid and then wash them again. It usually works...

Thank you!!

I haven't experienced this yet but I have found that plastic pots (like you get from the chinese) go greasy when washed in the sink, but are ok in the dishwasher. I found that drying them immediately with paper kitchen towels solved the problem - not sure how practical it would be to do with bottle teats but worth a try?
