When boiling baby bottles, there is a white residue left on the rim of the pan and on the bottles, what is it?
Quay asked:
When I boil my son’s bottles to sanitize them, there is a white residue left in a ring around the pan and sometimes even on the bottles themselves. I started using a water purifier and it still happens… does anyone know what the residue is and if it’s safe?

May 31, 2009 | 4:45 PMIt sounds like calcium deposits to me. They aren’t dangerous…it’s in your water…but because of the boiling point of the deposits and the boiling point of water the deposits get left over and the water boils off (vapor) - the deposits have to be heated to a higher temp than the water to become vapor.
The deposits start in the water as liquid, when you boil them they become solid…if you heated them up more than the boiling point of water (212 F - 100C) they’d “go away” ie: vaporize.
Try it with something glass…if it still happens that would be my guess. If it doesn’t I’d start to think about the plastic.
Sterilizing isn’t really necessary either - except the first time (when you take it out of the package) - I was shocked to hear that. My son’s doctor said that, and I looked it up and it’s true….but obviously, do what you are comfortable with.
