Does enfamil a+ stage 1 leave particulate residue in bottles?
In case of negligence, be it Enfamil or any other formula milk, you will see particulate residues in the bottle.
Before arriving at any decision, make sure you are dealing with milk residues and not dishwasher residues.
Personal Experience
I gave up using Enfamil when I noticed a thin layer of milk particles inside the bottle wall. Initially, my husband told me that it could be a thin layer of dishwasher residues. However, I was not comfortable with his idea. The reason being; before every feed, I used to clean my baby’s bottle with a bottle brush. To make it 100% bacteria free, I never missed sterilization.
After such a tough cleaning, there remains no question of dishwasher residues.
