Help! I am pulling my hair out - we are using SMA althera after bottle feeding breastmilk for 2.5 months.
Since the switch our bottles have been SO GREASY and oily. They have a load of residue on them no matter what I do. Even the Milton water ends up oily after I sterilise.
I have tried:
Milton bottle wash
Fairy liquid extra power
Leaving them to soak for hours in boiling hot water and soap
Using a combination of a dishmatic and bottle brush
Going over them multiple times
It can't be good to feed him using these but I don't have much choice. Nothing is cutting through the grease. Please help!!
