A few months ago I bottled using Wilko's Bruclens steriliser: http://www.wilko.com/homebrew-accessories+equipment/wilko-cleaner-and-steriliser-100g/invt/0022658
After sterilising I gave the bottles a few rinses with cold water. After bottling I noticed this white film on a number of the bottles: https://i.stack.imgur.com/Oi27E.jpg
My questions are: 1. Does this mean there is some steriliser left behind in the bottles? 2. What are the consequences if you consume some left-behind steriliser of this type with your beer?
Edit: I can't rule out that the film was caused by an oxi clean product from when I was cleaning the bottles, so it would be nice to know of any risks with that as well.
