Yes they are. I used tap water and didn't rinse them after, just put them on a rack to dry. @heera

Theyr brand new tho right??

You should only boil them for about five min or so. The bottles are fine tho. It has to do with mineral deposits that leave that film on there. Happened to me the other day. Did you use tap water? And did you rinse them off before or after you boiled them?

think u boil them too long
