Baby bottles had filmmleft over from breastmilk

I purchased a baby bundle of products from attitude when I was pregnant with my now 6 month old. I found that inhale to use a lot of the product to get a few baby bottles clean. It didn't sud and found that left a residue film from my breastmilk on the bottles and nipples. I liked that it was very natural and environmentally friendly but lacked the ability to clean effectively.
